Oh, Heavies aren't [i]that[/i] outclassed by Mediums when it comes to maneuverability- otherwise, there'd be no point in giving them all that heavy armor to begin with, they just wouldn't be able to keep up in regards to maximum speed, and would be a bit more unwieldy. Think Light-Medium-Heavy as Rogue-Fighter-Paladin for a rough comparison. 

Anyway, the rest of your fixes look good- except for the gatling cannon, no point in giving it magazines/reloads, especially since gatling weapons are belt fed. Just give it the a whole big number- 2000 might be a tad high, maybe go for 1500? An entire minute's worth of fire, is a [i]lot[/i] of fire.

Anyway, no further issues I can see from here, notify me if you intend to continue making edits. Other than that, I think Wes is good to go!

OH [@SirBeowulf], one last thing, sorry. How long has Wes been a part of the 7th Team? I want most(if not all)- minus the FNG/Maybe Team Leader of the squadron to have known/been with one another for a while.
