The Remote Anti-Armor Mine System (RAAMS) are two types of 155mm howitzer projectiles containing nine anti-tank mines each: the M718 or M718A1 (RAAM-L) with a self-destruct time over 24 hours and the M741 or M741A1 (RAAM-S) with a self-destruct time under 24 hours. Both projectiles are used with the M577 or M577A1 Mechanical Time and Superquick (MTSQ) fuze, which triggers the ejection mechanism of the mines above enemy territory after a preset time. Some 6000 have been sent to Ukraine.
