Semi-OT: Special Ops Mission
 

This is a TV series here in the US airing on the Military Channel. Technically, I guess it qualifies as reality TV, although it's basically a small-scale simulated special ops mission, with one operator (the same in all episodes) and an opfor of 4-6 people. Objectives and terrain vary in each episode. The missions do seem to be somewhat slanted in favor of the operator in that the opfor is not really large enough for the job it's supposed to do (and, as someone on IMdB pointed out, the opfor has very little time to train together, so it's not a very cohesive unit, despite all of them having military or police experience).

I mention this because it seems like the missions could be stealable as the basis for missions (more for Merc 2000, but some are applicable for T2K).

Here's the Wiki article, but be warned that it contains spoilers for most of the episodes:

One-man army against a bunch of guys who sometimes appear to be not working up to their potential...the show's not realistic, but it is fun to watch, and as you said, it provides some good adventure germs (but you'll have to expand it).

I've seen a few episodes, and I have to say it's been enjoyable. MAybe it is a little slanted, but what the heck. In most of the scenarios the OpFor is simulating groups that aren't really known for their cohesiveness.
