This made more sense to me when I first posted ... :P
Somewhere we talking about designing a carrier and what type of infantry it could hold ...
1. A better question might be: Are Inf Bays and BA Bays interchangeable? If you allotted 30 tons towards Bays (not compartments) would we be allowed to then designate on the fly (say before leaving planet-side) how it would be used? -- 10 tons for conventional Inf, and 20 towards BA.
A: my first thought was NO. BA Bays are just that, for BA only. Conventional Infantry are for PBI (and their variants -- motor, field gun, etc) only.
B: or is it YES, they are interchangeable and you need to make sure you take into account any extra personnel (for life support usage and stuff) you need as BA techs.
C. (really A part-2) If I put a 10-ton Infantry Bay in my dropship, as long as they remain as a full platoon I can fit any Conventional Infantry I want in there. BUT not BA.
(2nd post was wondering out loud about quartering infantry and how would you deal with their equipment -- especially motor/mechanized and field guns. I would think that their 'heavy' equipment would have to be removed from cargo -- OR you still have to make a bay for them, just not use it as such for super long treks)
good luck and I apologize for the ramble-ness!
