The Advanced Combat Helmet was developed and tested by Army Special Operations Command to replace the Personnel Armor System for Ground Troops, or PASGT, helmet. Various U.S. military units and services began fielding the ACH 2003.
Lighter than the previous PASGT infantry helmet, the ACH features a pre-drilled Night Vision Goggle (NVG) bracket hole. The helmet shell trim also eliminates the beak and has a higher side trim than the PASGT. The helmet also includes an improved 4-Point Retention and Pad Suspension System, which attaches at four points to the shell with ballistic resistant hardware. Adjustment slides are located on both the front and rear of the retention, allowing adjustment for proper fit and stability.
The Water Resistant Pad Suspension system supplied with each helmet consists of one crown pad, four lateral pads, and two front and rear pads.
