Mission is ok, but is lacking of something extra for example mines, asteroids, planets, probes, navbouys, satelites. Those are just add-ons to the mission but are missing here...
Although missions are simple converisons form orginal T/F missions CAB is v.OK with good plot and right number of imperial forces, so you don't have to act as "one man army" :P
If you want to destroy a bunch of rebel capital ships while they do NOTHING (M1,2,3) then this is a battle for you. In M4 and M5 creator is useing starfighter orders for capital ships :P, so in M5 you can outmaneuver CRS,CRL and frigate to crash to each other. And battle is VERY EASY. No challenge at all.
