Drawn in Colors 3D (because I'm poor and lazy). Also, I chose two of the most overused colors in the world. Also also, that's supposed to be an outline of a girl.
This sketch was a result of me brainstorming a complex equip system for an idea I had. Well, complex to me.
I'm a dumb kid.
There are 10 slots for a normal unit: Head, Eyes, Torso, Undershirt, Back, Main Hand, Off-Hand, Hands, Hip, Legs, and Feet. Most slots are pretty obvious as to what they're supposed to hold. Other slots, like Back and Hips, are for items like Backpacks (increase the unit's inventory), Quivers (increase arrow capacity), and Fuel Tanks (increases Flamethrower's fuel supply).
If simplification is needed, the stuff that would be combined would be Head and Eyes; Torso, Hands, and Undershirt; Back and Hip; and Legs and Feet. This would result in six equipment slots, which can be further reduced to Head, Armor, Main Hand, Off-Hand, and Back. Stuff like that.
Considering the whole '6-12 units per squad' thing, that would almost certainly be necessary.
