I'm not sure exactly what unloxks it but I don't think its time played. You said it may be 28 hours but I had 30+ and still hadn't unlocked the HARD missions. I think it may be rank or Matching Rate. I recently ranked up to First Lieutenant and and also broke 1500 Rate so it may be that. I have also seen low Rates with hard missions hosted but it may unlock once you've passed a set rate and stay unlocked even if you loose that rate later. Either way I hope the information helps. If no one can find it I may just start over from scrach and find out that way. Also just in case it's number of sorties I did 91 when I noticed they unlocked.

So for info to help find out for sure -

Rank - First Liuetenant, Sorties - 91 (72 online), Matching Rate - 1502, Time Played - 35:00,

Also please dont make fun of the people that passout while playing and have alot of time and crap rank lol.
