Human Factors Evaluation of the Modified AT-4 Light Antiarmor Weapon

Abstract

The AT-4 is a man-portable, 84-mm antiarmor weapon designed by the FFV Co. of Sweden who is represented in the United States by Honeywell Corp. This AT-4 evaluation was conducted in two parts. The first part addressed its durability, ruggedness, and compatibility with the marine rifleman's fighting load. This took place on the USAHEL (US Army Human Engineering Laboratory) cross-country and mobility/portability course. The second part examines the time it took marines to prepare the weapon for firing, and the frequency and type of errors they made during the preparation. Recommendations are made to improve the ruggedness, durability, and operational suitability of the AT-4. The AT-4 was found to be a rugged weapon that is fast and easy to prepare for firing. It was enthusiastically endorsed by the Marine test participants even though it is significantly larger and heavier than the lightweight antiarmor weapon (M72A1) with which they were familiar. Originator-supplied keywords include: Antitank weapons, Recoilless rifle, and Infantry weapons.
