Section II. OPERATION PROCEDURES
Before using the M966-mounted TOW/TOW 2, the squad must install the M220-series TOW launcher and encased missiles and must prepare the M966 for TOW firing. (To install an M220A1 TOW launcher and encased missiles on an M966, see TM 9-1425-472-12. To install an M220A2 TOW launcher and encased missiles on an M966, see TM 9-1425-450-12.)
3-4. EQUIPMENT STORAGE
The TOW system components are stored in the interior of the vehicle (Figure 3-2 [M220A1] and Figure 3-3 [M220A2]).
a. Six encased missiles are stowed in the missile racks on the left rear of the cargo area.
b. The traversing unit is stowed on the traversing unit adapter behind the right front passenger seat.
c. The MGS is stowed on the gunner's platform between the left and right rear passenger seat.
d. The nightsight and collimator are stowed on the right cargo shelf.
e. The launch tube is stowed on the right side of the cargo shell door.
f. The BPC and spare battery pack, or the nightsight coolant cartridges and the 4.8-volt nickel cadmium battery, are stowed in the floor bracket next to the right wall of the cargo shelf.

i. The tripod is stowed retracted, lying across the rear of the cargo area.
j. The TVPC is stowed in the MGS.
3-5. HMMWV INTERCHANGEABLE MOUNT SYSTEM
The HIMS is used to convert an M966 TOW HMMWV carrier into an automatic weapons platform (Figure 3-4). The HIMS provides units equipped with M966 TOW HMMWV carriers with low cost, quick, and effective options for tailoring forces for contingency missions. The HIMS contains two parts. (The HIMS technical data package contains the information needed to operate the HIMS and whereto find the materials needed. TM 9-2320-280-10 contains the combat loading plans for the vehicle.)
a. Part one is an armament mount panel assembly with pintle that mounts on the M1025 armament HMMWV carrier. This part is interchangeable with the missile guidance tray on the M966 TOW HMMWV carrier. The common turret ring of the two vehicles will accommodate the armament mount panel assembly using existing holes. No modifications are required.
b. Part two consists of a locally fabricated internal floor stowage plate that has automatic weapons stowage brackets, ammunition stowage trays, and footman tiedown straps already mounted for quicker emplacement. This plate is made of sheet aluminum and is mounted in the floor of the M966 TOW HMMWV carrier after removal of selected items of the TOW bracketry.
3-6. PREPARATION OF AN M966 FOR TOW FIRING
The three-man crew prepares the M966 for TOW firing by performing the following:
a. The gunner, driver-loader, and squad leader release the latches securing the hatch cover (Figure 3-5). The driver-loader enters the right rear passenger door.
b. The gunner removes the MGS from its stowed position.
(1) The gunner unlatches the retaining strap securing the MGS.
(2) The gunner releases the latches to remove the MGS cover and hands the cover to the squad leader.
(3) The squad leader stows the MGS cover in the front passenger's footwell of the vehicle.
(4) The gunner tilts the MGS to the vertical position on the gunner's platform and releases the lower coupling clamp on the traversing unit adapter.
c. The gunner positions the weapon station. The gunner opens the hatch and enters the weapon station, secures the hatch with the retaining latch, and rotates the weapon station by pulling upon the brake handle so that the backrest is toward the rear of the vehicle. To lock the weapon station, the gunner pushes down on the brake handle.
d. The gunner lifts the MGS through the weapon station, places it on the MGS tray, and secures it with the straps (Figure 3-6).
e. The gunner installs the traversing unit.
(1) The gunner opens the pedestal mount cover and secures it (Figure 3-7).
(2) The gunner lifts the traversing unit with adapter attached from the stowage base and secures the traversing unit to the pedestal mount with the coupling clamp ensuring that the traversing unit azimuth lock is toward the rear of the vehicle.
(3) The squad leader pulls the coil cable out of its retaining cup and hands it to the gunner (Figure 3-8).
f. The gunner connects the coil cable connector by aligning the yellow indexing line on the coil cable connector with the yellow indexing line on the J1 connector on the MGS (Figure 3-9). He turns the nut on the coil cable connector in the direction of the arrow until the red mark (band) on the M1 connector on the MGS cannot be seen. (Do not apply downward pressure on the coil cable connector. This can cause misalignment and bent pins.)
|
CAUTION Ensure that no dirt is in the end of the coil cable connector. Dirt can cause a bad connection with the MGS, resulting in poor system operations. |
NOTE: On the MGS for the basic TOW, push down to seat the coil cable connector on the M1 connector and tighten the locking nut.
g. The gunner installs the launch tube.
(1) The driver-loader uses the forward latch to open the cargo shell door and hands the launch tube to the gunner.
(2) The gunner installs the launch tube on the traversing unit and secures it with the launch tube latch (Figure 3-10).
h. The gunner installs the daysight tracker.
(1) The driver-loader hands the daysight tracker to the gunner.
(2) The gunner mounts the daysight tracker on the traversing unit boresight plate. He secures the daysight tracker-by locking the latch handle (Figure 3-11).
(3) The driver-loader stows the nightsight case in its bracket.
(4) The squad leader connects connector P2 of the TVPC power cable to the power conditioner cable.
(5) The squad leader unwinds the nightsight power conditioner cable and TVPC cable and hands both to the gunner.
(6) The gunner connects the nightsight power cable 2W2 to the nightsight input power conditioner J1 (Figure 3-12), then connects the TVPC power cable P1 to connector J1.
(7) The squad leader turns on the TVPC.
(8) The gunner turns on the power conditioner.
(9) The gunner checks steps 10 through 15 of system self-test on TOW 2 (positions 1 and 7 on basic TOW), then collimates the nightsight.
NOTE: The limiter assembly limits elevation to 20 degrees and depression to 10 degrees. If the limiter is used, the gunner makes sure both elevation and depression limiters are in the up position and pinned (Figure 3-13).
|
WARNING Injury to the gunner and damage to the equipment can occur if the TOW system is fired at angles greater than 20 degrees or less than -20 degrees for all firing positions except over the cargo shell door. If firing over the cargo shell door, firing angles should not be greater than 20 degrees or less than -13 degrees. Pressure waves and flying debris can cause injury to personnel and damage to equipment. |
3-7. LOADING, ARMING, AND UNLOADING
The procedures for loading, arming, and unloading the M966-mounted TOW/TOW 2 are as follows:
a. Load. Missiles must be unloaded from the missile racks in numerical order. The forward handling ring, preformed packing, and quick-release clamp are saved in case the missile is not fired. If missile diaphragms get damaged while loading, the missile can still be fired. The following procedures are performed to load the M966-mounted TOW/TOW 2
|
WARNING Never open one end of the cargo shell door until the opposite end is securely closed. Personnel injury, equipment damage, or mission abort will occur if both ends open at the same time. |
(1) On the traversing unit, the gunner ensures that the launch tube is locked in the 8-degree down position. He pushes the locking handle forward, then up, and opens the bridge clamp.
|
CAUTIONS 1. Do not drop an encased missile. Handling rings or launch container may be bent or damaged. 2. Do not break the diaphragm on the end of an encased missile. If water gets into the launcher container, the missile can be damaged. 3. Do not dispose of bad missiles. If an encased missile is damaged or handling rings are badly bent, return the encased missile to the ammunition unit for inspection. 4. Be careful not to punch a hole in an encased missile diaphragm when the forward handling ring is removed. |
(2) The driver-loader unlatches and raises the cargo shell door using the forward latch. He removes the quick-release clamp and forward handling ring from the encased missile.
|
WARNING Clear all personnel from the firing danger zone before proceeding with missile loading procedure. |
(a) The driver-loader turns the inside portion of the protective cover two complete turns counterclockwise, and he removes it from the electrical connector. (The protective cover is kept for future use.)
(b) He turns the encased missile so that the electrical connector is facing up and hands it to the gunner.
(3) The gunner takes the encased missile from the driver-loader. He raises the back end of the missile and slides it forward and down into the launch tube until the missile indexing lugs are firmly in place. The gunner lowers the back end of the encased missile ensuring that the electrical connector joins with the bridge clamp. He lowers the bridge clamp and pushes down on the top of it. He pulls the bridge clamp locking handle downward and backward to lock the encased missile in the launch tube.
|
DANGER Cargo shell door must be closed and securely latched at both ends before firing a missile. Firing a missile with the door not secure will cause injury to personnel, damage to equipment, or mission abort. |
b. Arm. The following procedures are performed to arm the M966-mounted TOW/TOW 2.
(1) The driver-loader closes the cargo shell door.
(2) The gunner makes sure the cargo shell door is securely latched at the forward end.
|
WARNING Do not raise arming lever until ready to fire at selected target. |
(3) The gunner checks the backblast area before raising the arming lever.
|
CAUTION Do not press the trigger with an empty missile case in the launch tube. Possible shorts can result, damaging the prefire, fire, and wirecutter circuits. |
c. Unload. The gunner lowers the trigger cover over the trigger after the missile has impacted and locks the traversing unit in the 8-degree down position. If a missile is prepared for firing and then not fired, it must be immediately tagged to show the time, date, and using unit. If the missile is not used within 90 days of initial preparation, it must be turned in to the ammunition supply point.
|
CAUTION If the missile is not fired, lower the arming lever before opening the bridge clamp. The command-link wires will be cut if the arming lever is not lowered. |
3-8. TARGET ENGAGEMENT
The crew members perform the following target engagement procedures.
a. When the squad leader issues the fire command, the gunner releases the azimuth and elevation locks on the traversing unit and turns on the nightsight if necessary. If crew members other than the gunner are in or leaning on the M966, they must be very still while the gunner is tracking. Even small movements can cause the vehicle to move and adversely affect the gunner's aim.
b. The gunner acquires and begins to track the target.
(1) If the target cannot be acquired in the sight, he announces, "Lost."
(2) When the target has been acquired, he identifies it as friendly or enemy.
(3) If the target cannot be identified, he announces, "Cannot identify."
(4) If the target is identified as enemy, he places the cross hairs on the center mass of the exposed portion of the target, presses the trigger, and smoothly tracks the target until missile impact.
(5) If the target is sighted out of the sector of fire, the gunner must rotate the weapon station to engage the target after the squad leader verifies the target's engageability.
3-9. IMMEDIATE ACTION
The crew members perform the following immediate action procedures in the event of a hangfire or misfire. If the gunner presses the trigger and nothing happens after 1.5 seconds, a misfire has occurred. If he presses the trigger and the pop of the explosive squib on the gyroscope is heard but the missile does not launch after 1.5 seconds, a hangfire has occurred.
|
DANGER The crew must use extreme care to avoid injury from a delayed missile launch. A delayed launch usually occurs within 1 minute. However, it could occur as long as 30 minutes after pressing the trigger. Keep all personnel out of firing danger zones. |
|
DANGER Do not open the cargo shell door during failure to launch procedures. Should the missile fire with the cargo shell door open, severe injury to personnel or damage to equipment will result. |
a. For a hangfire, the gunner alerts the crew by announcing, "Hangfire" and continues to track the target for one minute.
(1) If the missile fails to launch after one minute, he closes the trigger cover, lowers the arming lever and locks the elevation lock and the azimuth lock, ensuring that the launch tube is locked in the 8-degree down position (Figure 3-14).
NOTE: In a training situation, the crew dismounts the vehicle, closes the doors, calls EOD, and waits 30 minutes. The gunner may then remount the vehicle.
|
DANGER If the vehicle is not positioned with its front or rear in line with the target, it must be repositioned so that either the front or rear of the vehicle is in line with the target. The weapon station must be rotated during vehicle repositioning so the forward end of the missile is pointing toward the target at all times. |
(2) He opens the bridge clamp (Figure 3-15), removes the missile from the launch tube (keeping the missile pointed downrange at all times), and hands the missile over either side of the vehicle to the driver-loader (Figure 3-16).
|
WARNING Do not hand off a malfunctioned missile to the front or rear of the vehicle. A malfunctioned missile must be handed off from the vehicle to either the left or right side. |
(3) The driver-loader, keeping the missile pointed downrange, places the missile on the ground a safe distance from the vehicle. (In training, he places the missile on the ground at least 200 meters from the vehicle and marks the location.)
b. For a misfire, the gunner continues to track the target for one minute and presses the trigger again. He alerts the crew by announcing, "Misfire" and continues to track the target.
(1) If the missile still fails to launch, he disarms the missile by closing the trigger cover, lowers the arming lever, and locks the azimuth and elevation locks ensuring that the launch tube is locked in the 8-degree down position.
(a) The gunner presses the TEST-OPERATE switch to check the battery power. If he receives an OUT-OF-BAND/BATTERY FAIL, he checks to ensure that the TVPC switch is in the ON position and that the P1 cable is securely mated to the container. If all cables are connected securely, he replaces the power conditioner with a battery and checks the battery (Figure 3-17).
(b) He checks the coil cable connection to J1 connector. If it is not connected properly, he corrects it.
(c) He ensures the bridge clamp locking handle is properly seated, unlocks the azimuth and elevation locks, and raises the arming lever.
(d) He ensures the electrical connector is properly mated, raises the trigger cover, and presses the trigger.
(2) If the missile still fails to launch, the gunner may continue tracking the target for one minute (at the gunner's discretion in combat).
(a) He closes the trigger cover, lowers the arming lever, and locks the azimuth and elevation locks, ensuring the launch tube is locked in the 8-degree down position.
NOTE: In a training situation, the crew dismounts the vehicle, closes the doors, calls EOD, and waits 30 minutes. The gunner may then remount the vehicle.
|
DANGER If the vehicle is not positioned with its front or rear in line with the target, reposition it so that either the front or rear of the vehicle is in line with the target. Rotate the weapons station during vehicle repositioning so the forward end of the missile is pointing toward the target at all times. |
(b) The gunner opens the bridge clamp, removes the missile from the launch tube (keeping the missile pointed downrange at all times), and hands the missile over either side of the vehicle to the driver-loader.
|
WARNING Do not hand off malfunctioned missile to the front or rear of the vehicle. A malfunctioned missile must be handed off from the vehicle to either the left or right side. |
(3) The driver-loader, keeping the missile pointed downrange, places the missile on the ground a safe distance from launcher. (In training, he places the missile on the ground at least 200 meters from the launcher and marks the missile location.)
