Each round contains either the M718 or M718A1 (RAAM-L) mines, which have a self-destruct time over 48 hours; or the M741 or M741A1 (RAAM-S) mines, with a self-destruct time of approximately 4 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.^[2]

These mines can be delivered at ranges from 4 to 17.6 kilometres (2.5 to 10.9 mi) from the artillery battery position using the M109, M198, or M777 howitzers.^[3]

The United States sent about 10,200 RAAMS rounds to Ukraine between the start of the Russian invasion of Ukraine in February 2022 and January 2023.^[4][5][6]
