I've been looking up and down, but I can't seem to find the stats (Cost, modification slots, availibility, etc) for a lot of the modifications listed in Arsenal, under "Military-grade Armor Enhanements". Many were restatements of various cyberware pieces, and they said so in the description. However, there are many (such as the flotation system, mobility upgrade, quick release, and strength upgrade), which have no stats whatsoever, or at least one that I can find.
Am I missing something, or are there genuinely no statistics available? If there aren't what would you do?
