Anyone know of any games like Americas Army, only on lower spec.

Please don't suggest:
-Counter Strike: Despite the fact its a FPS, it's nothing like AA.
-True Combat Elite: Closest I have found, but I really want one with an honor system like AA.
-Any FPS like Counter Strike: You know what I mean, mindless team deathmatch. I like realistic, tactical stuff.

It doesn't have to be free, I don't mind spending money. It's just got to be lower spec then AA cause since a few versions ago, AA no longer runs well on my PC.

Umm. well i played AA for atleast 30mins and deleted it. soldier front was ok.. if u mean by honor system, like ranks, u should check out soldier front. it didn't lag on my computer.

Warrock has aspects of both AA and CS..however..it's just gone retail.

I played it in open beta and thought it was an awesome game.

There are many vehicles including:

Dirtbike
Heavy duty tank
Light tank
Passenger helicopter
Offensive helicopter
Speedboat
Armoured boat

There's a ranking system where you gain a new badge as you level up. :p

I'm not sure if it's lower specs than AA though.

SF is more ping-friendly than other FPS (you can still kill people if you dont live next door to the server)
