Shit, totally forgot to mention something about the staffing on the island - I've added it into the IC! (TLDR there's a few support staff NPCs on the other side of the isle including an engineering, vehicle maintainance, logistics and general purpose signal intel team, stuff gets brought in periodically- that includes everything the team needs.)

I'd put them more a blend of the "Pilots" from Titanfall 2 (whose setup for combat/lore I fucking adore) - and perhaps the exos from COD Advanced Warfare on top of what you mention. Pretty much the idea of a character that can carry a fuckload of momentum but still carry a decent arsenal- the exo basically just helping to lift the weight that comes with taking a versatile loadout.
