Research
Spending a vehicle's experience to unlock its modules and the vehicles that follow it in the tree.
Also known as grind, unlocking, researching.
Experience earned in a vehicle is spent from that vehicle. It buys its own upgrades first, tracks, engine, turret, gun, radio, and then the next vehicles in the branch.
The unlock and the purchase are separate: research makes a vehicle available, credits buy it. A player can therefore be several vehicles ahead in research and unable to afford any of them.
