A concept drawing for the ET-MP. U.S. Army Research, Development and Engineering Command illustration Currently, the Army possesses the spherical, nearly-baseball-sized M67 as its primary hand grenade. Soldiers often carry other types of less-lethal grenades which can create disorienting noise and flashes, illumination, or intense heat for destroying equipment. The Army formerly fielded concussion grenades known as MK3A2s, which began as bunker-clearing weapons during World War I. Shaped like a beer can, these kill or incapacitate enemy troops when detonated inside confined spaces as the blast pressure reverberates off the walls. Soldiers frequently lobbed them on the battlefield, so much so that concussion grenades amounted to the second most common type tossed by U.S. soldiers during the Vietnam War, according to a 1969 Army study of 17 infantry fighting in the conflict. Fragmentation grenades, which kill by blasting out small metal fragments, were the most popular. But the MK3A2 was a danger to U.S. troops. The grenade’s exterior coating contained up to 50 percent asbestos, which can spread microscopic fibers that pose serious health dangers if inhaled. You definitely wouldn’t want to breath deeply while clearing a room after detonating one inside.
The Army withdrew the MK3A2 from service in 1975, according to Picatinny. Frags and stun grenades, such as the current M84 flashbang, took its place. But in a few years, soldiers could have them again in a two-for-one. As concussion grenades have a smaller lethal blast radius than fragmentation grenades, it’d give troops more flexibility when clearing obstacles. There’s one more improvement with the ET-MP — it’s ambidextrous. That’s important because the current M67 was designed for right-handed soldiers, so the Army trains left-handed troops to flip the grenade upside down, holding the safety lever down with the left thumb, while pulling out the ring with the opposite hand. But that can be awkward for lefties to handle. When dealing with a weapon where a single fumble can kill the thrower and the people around them, awkward is a word you don’t want to hear.

Air Force Reserve ► New Commander's Goals In June, Lt. Gen. Maryanne Miller was chosen to serve as the first female commander of the Air Force Reserve — a position that makes her one of the highest ranking women in the military. And over the four years she will spend in the post, she intends to leave her mark by making the Air Force Reserve a diverse component of the armed forces, with an important role for anyone who volunteers to join. As she entered the New York City Air Force public affairs office conference room with a press officer and her sister, she wore a kind smile. She had piercing blue eyes and a firm handshake, and as she greeted her interviewer, she remarked that she was looking forward to visiting the 9/11 Memorial after the interview but was very happy to have had the chance to sit down with Task & Purpose.
