HE Bolt

The HE Bolt is an unlockable ammo type for the XBOW in Battlefield 3

Battlefield 3
"High explosive bolt against vehicles with almost no splash damage and a short trajectory."

- Battlelog description

The High Explosive Bolt is tipped with C4 that explodes on impact. It does not deal as much damage as an actual C4 charge or an RPG shot, but it can still disable scout choppers (AH-6 and Z-11W) and light transports in a single shot, and take out small groups of infantry, although the explosive radius is the smallest of any explosive device in the game.
