I call ****. I did everything you've described in my supersoldier runthrough, and I'm pretty sure it took longer than that.

Yeah, three hours doesn't sound realistic. You also can't run past everything, there's a number of spots in the game where you have to switch to the Covert Ops upgrade to get through because the environments are too tight. And there's a couple of heavies that you have to blow up for the next objective to unlock.

It's true that it's too easy to just stealth through almost everything, though.

You do also realise that you don't have to wait 6 months right?

Just go to your PS3, set the date 6 months forward, load up game and play. DING trophy.
Quit and put date back to original.

Almost 10 hours beating on my first playthrough then played it on Supersoldier, checked on my stats. 12 hours and 45 minutes.

Edit:

heres the pic BUT the game was also adding time while i was doing a Souvenir, Dogtags, Car Keys & Speed Cams trophy hunting(im not even done yet). oh btw im not forcing you to believe it

My first playthrough was on SS including some dikeing around and collectible hunting etc and I got done just over 9 hours. When I went back through to pick up missing collectibles I pretty much ran through massive sections not caring about stealth or engaging and then when the enemies eventually catch up with you they are easily picked off as they approach, so i would imagine If you really focussed on a quick run through (especially having already played through the campaign) you could chop of a significant portion of time

That reminds me, I still have my Supersoldier progress at 18/19, even though I've now completed the last level twice. It jumped to 19 briefly, then reset to 18. LOL.

Naw, doesn't work for this game, its an online trophy.

took me 10 hours on supersoldier, the first time. I loved it, cause it was a real challange, i died a lot and took my time and plannen my kills

one of the best singleplayers ever imo.
