Thanks for the kind words, everyone! The figure IDs are just as Dentatus says, Warzone and Trinity Battleground. Dentatus should know: he painted the bald woman!

The camo pattern grav AFVs are indeed old computer mice, with 20mm square figure bases, dollar tree kids puzzle pieces, and caps from our diabetic cat's insulin syringes all added. The camp itself is about the only type of vehicle camp I can paint that doesn't look awful. It's easy to do, but time consuming.
The big unpainted hover tank is actually a kids toy jet ski hull, flipped over and with a dollar store tank turret added.
