The US military is getting its first new hand grenade in 40 years as engineers at the US Army Armament Research, Development, and Engineering Center (ARDEC) at Picatinny Arsenal, New Jersey, work on a safer multi-purpose design. Called the Enhanced Tactical Multi-Purpose (ET-MP) hand grenade, it will allow soldiers to choose between concussive or fragmentation blasts with the flip of a lever.
Though many people think of grenades as little green pineapples with pins sticking out of them, there are actually many different types for many different jobs. There are incendiary grenades for destroying equipment, gas grenades for crowd control, smoke grenades, stun grenades, anti-tank grenades, and even illumination grenades to cast a bit of light on the subject.
The two main lethal types carried by foot soldiers are concussion and fragmentation grenades.
Concussion grenades are listed as “offensive” because they kill by means of blast. They have a small danger radius, so soldiers can use them while advancing in the open without fear of being caught in the blast wave.
