ARMA 2 OA patch 1.57 textures look bland on PMC, BAF. Why?

I installed the 1.57 patch and it added the PMC and BAF to the list of units. I didn't get the expansion with the BAF, nor did I get the PMC expansion yet. When I start a game with any of the BAF or PMC units, the detail on their bodies looks far less detailed. Their clothes look like a basic rendering.

Is this because I don't have those other expansions installed? Should the models render out in detail even though I don't have the expansion?

It is like the 1.57 patch to OA comes with extras for the other expansions. It also added Shapur and Proving Grounds to the map list.

Without the DLC purchased you get only low detail textures on BAF and PMC units, vehicles and maps.
