Precision

Description
Precision ammunition can be used in standard autocannons and their lighter cousins. Scientists from the Federated Suns managed to modify autocannon ammunition to accommodate a gyrojet shell that can correct its course in mid-flight, but the course correction system increased the mass of each shell. Debuting in 3062, precision ammo soon found its way into the armies of other nations.

Game Rules
In CBT play, precision ammunition grants the firer a 2 point reduction to the Target Movement Modifier. This comes at a cost, however, of only being able to carry half as many rounds per ton (round down).
