What it says on the tin. Add a few of the ESFs and liberators to each VR Training, "flying" even if they're static so players can have the opportunity to shoot at them from the ground (G2A) or from the air (A2A).
Theres a lot I'd like to see in VR training that I think could be added. Honestly expand the area and add a building of each type normally in most bases. I feel like having an infantry shooting gallery where the targets run back and forth would be nice, have a few like aircraft that just fly in a circle constantly too. Things like that.
