It may not be your thing necessarily, but Steel Armour: Blaze of War, has an Afghan scenario.
It's a tank sim, not a wargame, but it's built on the same basis as Operation Star. You do command forces on a tactical level. Either just the armour, or you can also do everything. Bit more detached than Operation Star for commanding though, as you're locked in a tank (think, using the map to tell units where to go), but it's quality.
The Afghan scenario in SABOW has you going up against insurgents with insurgent tier equipment, as opposed to Operation Star that tried to level the playing field by giving significant Iranian armour support. The battlefield also has a more Afghan feel to it.
I found it quite comfy at least.
With regards to Chechnya, I feel you. I want to say Squad has such factions available, but that's a very different genre.
