Maybe the Type-1 and Type-2 mating works like this:
In various combinations, the advantages could be:
1.) The Type-1 has the phased energy generation gizmos, but it uses the extended power pack and the emitter and cooling units of the Type-2 body. Cost savings. The expensive parts are probably the phased energy generator parts.
2.) The Type-1 has the electronics/computer control (brains) and the Type-2 is the dummy unit (brawn). Again, the expensive part would be the controlling unit.
3.) Combination of 1 and 2 above.
4.) You'd never use a combination of Type-1s and Type-2s, either force needs to be discrete (and unlikely needed), or it's needed. You'd not need to hide weapons and have very visible ones at the same time. So why duplicate control electronics and duplicate other crucial parts?
