There was an implication that JA2 "headgear freedom" didn't offer any choice or offered less choice. I simply gave an example where this wasn't the case.
I also wrote about the late game in the message above yours... to add to that, I checked a savegame on day 70+ and Bobby Ray's didn't have any NVG on sale, so I don't think it's trivial to get the absolutely best gear for all mercs later in JA2.
In JA1 you had only one slot for weapon accessories, so you could either attach a scope or a silencer. Is this a better system than in JA2 which allows both of these to be attached at the same time?
