USGI ACU Interceptor Plate CarrierNote* No inserts, plates or extra pouches are included vest only. The Interceptor multi threat Body Armour system (IBA) was the replacement armour system that came out in the 2000s to replace the PASGT system. The core component was these OTV (Outer Tactical Vest) vests. With these you could add all the pouches you could possibly need to sustain combat in the short term as well as attach other protective components such as groin or neck protectors.
