HOWITZER
DIRECT FIRE RANGE CARD
Direct fire range cards should be completed for all howitzers in their primary, alternate, and supplemental positions. This checklist could be used when constructing a direct fire range card:
_____ Have you walked the terrain?
_____ Have you identified your left and right deflection limits?
_____ Have you identified reference points, the deflection, quadrant and range to those reference points?
_____ Have you assigned the appropriate shell fuze combination to those reference points based on range and expected targets.
_____ Have you covered any dead space with M18A1 claymore, M203,or the MK-19?
M119 Howitzer:
_____ Anti-personnel targets 275-400 use APERS.
_____ APERS targets designated as Charge 6 or 7?
_____ Close-in APERS targets annotated as muzzle action?
_____ Killer Junior targets 400 meters or greater? Closer than 400 meters the fuze function is unreliable.
M198 Howitzer:
_____ Engage targets closer than 800 meters in combat only.
_____ Targets above or below howitzer require computation by FDC.
_____ Use of other than maximum charge require computation by FDC. (Killer Junior).
_____ Apply observer target factor.
_____ Prepare range card IAW FM 6-50, page 3-12.
**Note: No firing over friendly troops. Central laying is the prefered method.
