Why not use them for fun? Especially if you have them laying around. Later I'll build a force that uses the same bases as the mecha so the blast templates work properly. A single vehicle should be based alone. Infantry teams go on the same base with 3-6 miniatures each. ATGM teams should have a ATGM team modeled.
Note: all conventional units follow the basic rules of the game except where noted below. All units below are US Army formations because I'm an old G.I. Feel free to build your own force of choice.

Make up your own point values… I don't really use them. Other nationional forces could easily be built off these templates. I'm thinking about an EBSIS force with T-80 tanks and Khurasan 15mm walkers as battloids.
