I want the stealth suits a lot more than the power armor.
Oooooh. Take my money already. I've always been more of a stealth suit - stealth sniper kinda guy.
For the most part, it doesn't need to go everywhere the troops can go. Size will be a limitation more than terrain in many situations such as urban combat (think clearing buildings).
Well, you guys having the discussion need to clarify your use case before you start "debating" the details. When each person has a different mental picture of the CONOPs for the platform in question, you'll always be arguing at cross purposes and it'll never go anywhere ... which happens all to often on forums.
I have no dog (heh) in this fight so I have no more to add to the debate.
