The Deltoid Axillary Protector (DAP) (or Deltoid Axillary Protection System, DAPS) was developed in response to the improvised explosive device (IED) threats that soldiers face in Iraq. Unlike conventional threats, which usually come from the front, back, or above, IEDs throw shrapnel and spall at soldiers from below and from the sides. DAP enables soldiers to cover shoulder and upper arm areas as well as the armpit and underarm. The original Interceptor body armor design is open around the arms to allow air to circulate.

The Outer Tactical Vest (OTV) provides protection from conventional fragmenting munitions and multiple hits from 9mm handgun rounds.

The OTV groin protector provides additional protection for the femoral arteries and pelvis. The groin protector attaches to the inside of the front carrier using two nylon straps and snap fasteners.

The OTV throat protector provides additional ballistic protection to the throat.

The OTV yoke/collar assembly provides additional ballistic protection to the back of the neck and shoulders.

The Enhanced Side Ballistic Insert (ESBI) plates provide additional coverage as they protect the wearer's sides between the Enhanced Small Arms Protective Insert (ESAPI) plates worn inside the front and rear, and provide the same ballistic protection as the ESAPI.

The Enhanced Side Small Arms Protective Insert (S-SAPI) and ballistic carriers provide increased side torso protection for Marines.
