Do a test with these two units first, thank you.
I am pissed because in COH2 these two guys barrage are actually different and relatively inaccurate, you are NOT rewarding by manually barrage the target.
Pack Howie barrage just shoot 3 or 4 so-call anti-tank round basically does nothing, and have a long cooldown. If you leave it auto-fire, it is just shooting non-stop.
Same logic for the LeIG, the difference only the cool-down isn't that stupid long, just auto-fire still WTFBBQPwn.
You can't be good in this game if you still haven't understood its basic concepts. If you want to play a game that has no RNG involved, go play chess.
And manual barraging is quite rewarding, you just need to know when and where to do it
