Interim Small Arms Protective Overvest

The Interim Small Arms Protective Overvest is an expedient solution to achieve a modular small arms protection upgrade to the fielded Personnel Armor System for Group Troops (PASGT) fragmentation protective armored vest (commonly referred to as the flak jacket). The ISAPO is worn over the PASGT vest to provide front and back protection against small arms and flechette threats. ISAPO can also be worn with the Ranger Body Armor (RBA) to add small arms protection to the back. ISAPO is compatible with fielded load bearing equipment and protective Clothing & Individual Equipment. It weighs approximately 16.5 pounds and consists of two components: a carrier and a pair of ceramic small arms protective plates.

ISAPO was approved for MS III in March 1996 with the intention of a one-time procurement of 4000 overvests for Army contingency purposes. The ISAPO will be available for use until the full solution (Modular Body Armor) is fielded in FY99. ISAPO will be available in Woodland and Desert camouflage patterns.

ISAPO provides the same level of small arms protection as the RBA. However, the area of fragmentation protection is greater using the ISAPO/PASGT combination than with the RBA, and small arms protection is greater covering front and back torso then RBA with front plate alone. The cost of providing ISAPO is approximately half the cost of RBA (the PASGT vest has already been issued).

The Army identified an urgent need for body armor that protects soldiers from the small arms threat. As a result, the Army developed and procured 4000 sets of the Interim Small Arms Protective Overvest (ISAPO). The ISAPO overvests are worn with the PASGT vest and provide protection to the areas covered by the ISAPO plates against small arms fire up to and including the 7.62 millimeter rounds. These 4000 sets of ISAPO were held in Army contingency stocks for units identified to respond to a crisis and will face a small arms threat.

The 4000 ISAPO one-time procurement was conducted by U.S. Army Soldier Systems Command (SSCOM). ISAPO components will also be available through GSA Federal Supply if additional quantities are required in the future. Estimated ISAPO unit cost is $330.00.

From the 4000 ISAPO supply, 1146 ISAPOs were provided to support USAREUR mobile and dismounted Military Police in Task Force Eagle under Operation Joint Endeavor. The balance of 2854 ISAPO will be available from a single depot for contingency purposes. Contingency Stock will be managed by PM-Soldier.

The Central Funding and Fielding (CFF) program purchased the 4000 ISAPOs for contingency use.

Realizing the need for one system to defeat the small arms threat, the Army began fielding in fiscal year 2000(FY00) the Interceptor Modular body Armor system. The Interceptor Modular body Armor is a joint program with Army and the Marine Corps and will replace the PASGT vest. The system is capable of withstanding multiple hits from 7.62 millimeter rounds and has attachable throat and groin plates for increased protection. In FY99 the Army procured 4000 set of Interceptor Modular Body Armor for delivery in FY00. The 4000 set replaced the 4000 set of ISAPO in the aforementioned Army contingency stocks. Although the Army began procuring Interceptor Modular Body Armor in FY99, at that the plans provided only limited quantities of body armor capable of defeating the small arms threat until FY08.

Interceptor is the model name for the joint Marine Corps/Army body armor system. The modular body armor system consists of a vest with protective plate inserts front and back. Interceptor is up to 40 percent lighter, with more protection than the previous generation of body armor, the PASGT vest. Users can tailor the ballistic protection worn to the level of threat, weight and mobility priorities. Individual components or sub-components can be replaced or upgraded. Interceptor provides the wearer with improved fragmentation protection plus 9mm bullet protection at a weight savings of about 18% over the PASGT vest it replaces.
