I've got nothing against a CO's decision to deploy. I understand the reason behind that, be it for the morale or to allow themselves quicker coordination, but...
...as a squad medic enthusiast, I noticed whenever the CO gets in a dangerous situation and take some hefty damage as long with a bunch of marines, those combat ready marines get left out in the open or ignored for some amount of time.
The CO could be the brains of the whole op, sure, but that marine has a bigger potential in combat situations since they're focus is not to command or be in touch with everyone, but keep xenos at bay with their equipment or outright kill them.
Thoughts?
