The Military Hardware the FedSun have are mostly excellent, hoever, the changes they did to their Military structure has had the most grave consequenses.
IMHO especially the LCTs are a failure. And they they seemingly are not capable to adapt to the new situation post-Grey Monday..
LCTs were a good concept: Units that they knew they could move to where they needed to go. Where they ran into the
problem is that, with HPGs down, they cannot easily know where they need to send those LCTs in time fo rhtem to do any
good. Even with black boxes, it could take a few days for the word to reach the right people, then a few days to coordinate
the jumps, then a couple days to make the jumps(as they have to jump, then switch jumpships to jump again). By that time,
a planet could already have more or less fallen, or the Confederation or Combine could have reinforcements arriving and ready.
With the HPGs down, frankly, the universe favors an attacker more then it favors a defender right now. Davion's Castle Doctrine
is, in practice, similar to the Confederation's Elastic Defense doctrine, and is proving to be as effective at dealing with multiple
waves of attacks..
