Notes:

– All single-shot BFD limits are at 44mm. Mean BFD is limited to 25mm on HO3, HO4, and SG1. – Three shots per armor panel are placed on size S soft armor panels. Seven shots per panel are placed on soft armor panels in sizes M and L. – Three shots per plate are placed on hard armor plates tested to HO3 and HO4. – One shot is placed on hard armor plates tested to SG1. – There is an optional “special threat” protocol which includes M855 and .357 Magnum, but the use of this protocol is optional, and these threats are not assigned a level. Oddly, under this special threat protocol, the BFD limit for M855 is 30mm, rather than the 44mm that is listed for all other threats.
