Precision ammunition
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,[1] precision ammo soon found its way into the armies of other nations.

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).[2][3]
