The APC models are Rafm "Imp". A nice 6x6 wheeled APC with three turret options (no weapon, generic twin barrel weapon or twin box missile launcher (AT or MRL).
For a platoon command/support element, I've got a Rebel Miniatures Comanche MATV. It fits the general concept of the mid-tech PDF - a robust 4x4 vehicle with a substantial support weapon mounted up top.
And lastly, the vehicles for the platoon are ranked up here...
I'm happy with how the vehicles turned out. Assembling the Imp is a post for another day!
