Could the Army’s next medium machine gun be featured at this year’s SHOT Show? SIG Sauer believes so. Among the numerous new weapons, gadgets, and coffee mugs unveiled in Las Vegas during the 2019 Shooting, Hunting, and Outdoor Trade (SHOT) Show, there was also the SIG Sauer Lightweight Machine Gun (SLMG).

SIG aims to win the United States Special Operations Command’s (SOCOM), Army’s, and Marine Corps’ Squad Automatic Weapon (SAW) contract for a new medium machine gun with this belt-fed platform. But what’s so special about it?

First, it weighs a lot less than the current M240B: It’s seven pounds lighter. Throughout the history of war, lighter means better. Whether one is talking about the Greek hoplites who fought the Persians at Thermopylae or U.S. Marines battling it out with the Taliban in the mountains of Afghanistan, the goal has always been to be as lethal as possible without any unnecessary weight. If seven pounds could be shaved off by a better weapon, that means warfighters could carry more ammunition and thus be more lethal.
