Once Newland and Natick's Quick Reaction Cell heard about the battlefield invention, they worked with other military agencies to make the device into something that could become official Army gear. The device even got its first trial-by-fire in an ambush on Feb. Vincent Winkowski, decided to put together the do-it-yourself pack after another soldier mentioned the mini-gun ammunition carrier worn by actor Jesse Ventura in "Predator," according to Soldiers magazine. The idea first came from an Iowa National Guard unit that was discussing the machine gunners' troubles in the aftermath of a two and a half hour firefight in 2011. "It just made it more efficient for an individual gunner to execute his mission in that way." Army's Natick Soldier Research Development and Engineering Center. "As a single gunner, that's lead on target for 500 continuous rounds of ammunition fired in bursts," said Sam Newland, Quick Reaction coordinator for the U.S. The Army originally meant for crews of two or three soldiers to fire and reload the M240 machine gun, but some Army machine gunners in Afghanistan have ended up struggling to do everything alone and reloading every 50 or 100 rounds - raising the risk of the weapon jamming and cutting back on the rate of support fire for fellow soldiers. The "Ironman" pack allows a single machine gunner to carry and fire up to 500 rounds of ammunition in combat without pausing to reload.

Their battlefield invention has since undergone official Army development and testing among several units deployed in Afghanistan. soldiers wanted a way to handle heavy machine guns and ammunition alone in the heat of battle, they found inspiration in the mini-gun backpacks of the 1987 film "Predator" and built do-it-yourself ammo carriers.
