Codes are quite balanced at the moment. Additionally they are required to add some diversity to civilian loadouts.
If you want to use Codes on a Transport, simply equip an Armored Transport with them. Two 600-projectile-speed Codes with a 4.0 refire match well with the 600-speed Transport turrets (type 1 and 2).
Bigger Transports don't work well in fights and the variety of Transport-Turrets with 8 (effectively only 4) different types is good, too.
