Combat, what's the deal?

I think the best way to kill enemy fleets is to have a fleet of your own
Joining up with a TCN fleet, or having a squadron of fighters deployed are the easiest methods.

Especially with fighters, you can hit them, then recharge quickly and send 'em out for another attack.
If you have multiple fighter bays, you can recover and repair the damaged ones while the rest continue to pound the enemy to dust.
