1.1 This practice provides measurement and fit guidance for soft ballistic-resistant or stab-resistant body armor, or both, covering the torso. Proper measurement of the wearer and fitting of armor to that individual are necessary to obtain sufficient coverage of the torso and vital organs while allowing the full range of motion required for officer operations.
1.2 This practice is primarily directed toward law enforcement and corrections officers and addresses measurements for and fit of normal duty body armor worn under or over the uniform for both male and female wearers.
1.2.1 Normal duty body armor may be concealable body armor (see 3.1.8) or outer carrier body armor (see 3.1.13).
Note 1: Types of outer carrier body armor include load-bearing vests, tactical body armor, and plate carrier.
1.2.2 Body armor addressed by this practice is composed of front and back protective panels contained within a carrier that positions and holds the panels on the torso. Side coverage may be accomplished by either the front and back panels overlapping on the sides or by having a cummerbund accessory (see 3.1.1).
1.3 This practice can be used to train individuals on proper measurement techniques and to train wearers on proper fitting of body armor.
