Rocket-assisted projectiles are available for the 105-mm and 155-mm howitzers. They are designed to
extend the range of the howitzers. The basic rocket-assisted projectiles are filled with HE material.
They produce blast and fragmentation in the target area. Computation procedures for the two basic
HE RAPs are identical.
The 105-mm RAPs are the M548 and M913. The 155-mm projectiles are the M549 and M549A1. For the M109A2/A3
weapons, these projectiles are fired with charges 7 (M4A2), 8 (M119A1), and 7 (M119A2). The M198 howitzers may use
charges 7 (M4A2), 8 (M119A1), 7 (M119A2), and 8S (M203 only for the M549A1 projectile).
