Survivability Onion Description

Armored vehicle with explanations of levels of protection
There are four levels in the EODC “Survivability Onion” diagram, represented by concentric circles resembling the layers of an onion. At the centre of the onion, the vehicle is pictured.

The outer level is AMAP™-S, with the subtitle “Don’t Be Seen”, and is the best way to keep the vehicle and its occupants safe. Using coatings, materials, radar signature reduction, thermal signature reduction, acoustic signature reduction, visual signature reduction, active signature reduction and shaping makes the vehicle more difficult to detect.

In the event that the vehicle is detected, the second level is AMAP™-ADS, with the goal “don’t be hit”. It employs EFP-protection, IED-protection, KE-protection, Active Defence System, RPG-protection and AT-protection.

If the vehicle sustains a hit, the goal becomes “don’t be penetrated”, which is the third layer of the onion. Many protection systems come into play: AMAP™-P (Passive Statistical Defence System), AMAP™-SC (Shaped Charge), AMAP™-IED (IED Protection), AMAP™-B (Ballistic Protection), AMAP™-M (Mine Protection), AMAP™-T (Transparent Armor), and AMAP™-R (Roof Protection).

The final layer of the “Survivability Onion” is used if the vehicle is penetrated. The purpose of this layer is “don’t be killed”, and includes AMAP™-MPS (Mine Protection Seats), and AMAP™-L (Liner Systems).
