It is effective against vehicles, craft, and infantry, regardless of shielding. It's armor-piercing nature is the reason for its effectiveness against vehicles; armor piercing rounds are designed to shoot through armor to damage the occupants of the vehicle. While unshielded infantry are easily killed, Energy Shielding defeats most of the armor-piercing benefits of this round. However, it is still effective due to its large size and high kinetic energy. Only the Sniper Rifle System 99C-Series 2 Anti-Matériel uses a larger round.
This round should not be confused with the M225 SAP-HE rounds that are used with the M6 Series pistol. The pistol rounds are smaller, with less powder and thus lower muzzle velocity and kinetic energy. They also operate on a different system, mixing both armor-piercing and high-explosive properties. This round is not high-explosive.
