With Formation benefits combined with a good enough pilot, it is possible to get Marksman, Sharpshooter, and Human TRO on the same pilot (Marksman from a Command Lance and Sharpshooter+ Human TRO via standard purchase on 1 unit per 12).
They don't prohibit stacking explicitly in their rules text, at least that I can find, so could I, if standing still, possibly trigger all 3 on one shot (once per game for Human TRO). If so, how would Marksman's "half damage" and Sharpshooter's "full damage" interact, and how many crit chances would there be?
I imagine, based on the flavor text, that Marksman and Sharpshooter are supposed to be mutually exclusive, since the latter is an "upgrade," but right now there's nothing indicating that, so I'm asking.
