The Colonial Militia Act required Federation colonies to raise and support these light infantry units. In times of dire need the forces guarding a colony may be "stiffened" with cadres of Amazons and Valkyries.
Colonial troopers are armed with cone rifles. They do not wear body armor or use jetpacks. Some colonies can afford to equip their militia units with grav vehicles; others may provide scouts with grav-sleds or tracked vehicles.
