They are more like that, Squad actually was made from people that made a mod for Battlefield 2 or 3(I don't know which) called Project Reality and Squad itself is basically Project Reality but made on it's own engine. It's like battlefield but the maps are much bigger and you don't respawn at captured points, instead you have to build spawn points and to do that you need supply and to get that you need logi trucks. You also have to join a squad in that game, it's heavily team work based. ARMA shares a lot of those features but it has a single player campaign and the multiplayer isn't as rigid or Battlefieldesque.

Insurgency is more like a swat game though. I did not play it much because I don't like Swat games, but the shooting was good.
