A day will come when there will be adverts in the game (I know NHL 200x and Nascar series have them already) but imagine adverts in OFP.
"LEADER: 2,3,4 Attack PEPSI T-80, 4 o'clock"
"LEADER: 3, move to TACO BELL, 1 o'clock"
And there would be adverts on the side of the vehicles, like Smirnoff ads plastered on side of Russian tanks, or soft-drink billboards on the side of the road.  Or when the A-10 flys, it pulls an arial sign "Just Do It" or something.  This day will come, just wait and see.  I'm sure marketing suits are saying "All kids/adults are playing computer games and aren't watching any adverts while playing, how can we tap into this market?" And some  other a-hole in a cheap suite suggests "I know, let's buy ad space in games. We'll sponser different vehicles and place adverts on billboards in the game."
Imagine driving you Levis Jeep north to Houdan, just when you come over the hill, you see the familiar yellow glow of the Golden Arches greating you.
