No railguns in the fleet. No energy weapons either. It's a moon with automines on it and that is uninhabitable already. If railguns are the cleanest option, I may need to pull a point defense ship off the front line to use the CIWS on them.
I haven't found the enemy colony yet, so trying to use this moon as a test for softening up the ground troops. Trying to figure out if the chance for ground troop destruction is based on warhead size, number of warheads, or just a flat chance per salvo.
