Question: Where do I sign up if I want to be trained and equipped with a suit of power armour?
Answer:
Power armor is still experimental; few (if any) nations see the advantage of outfitting infantry with bulky armored suits compared to sending in tanks and close air support, and the R&D investment necessary basically blocks off the technology for the foreseeable future. The "light" armor of infantry is substantially stronger and covering than the armor of today, and most are climate controlled; it's just that nobody has made the leap to adding robotic support into the suits. If you're dead set on working with power armor, consider contacting Weir Labs; they're always working on something that is new, experimental, or highly dangerous, so they're almost definitely working on power armor. Also, they have such a high turnover in test subjects, that test subjects can work with almost any project that is being worked on.
Question: Are these armies gearing up for wars that have never come yet, or have there been grand interstellar conflicts?
