It would add some interesting arena dynamics to make it possible for players to be able to deploy a temporary Forward Operating Base, or FOB. I would envision this as a special mission type, where some minimum number of players would roll a group of C-47s that would then fly to a non-base spot on the map and land together. Upon deploying their field cargo, the FOB would build over time into either a Vehicle base or airfield with limited capabilities. A marston-matt runway, tents instead of permanent buildings, open-air fuel and ammo dumps, and light AA would make up the field. The field would remain operational for a set amount of time (30-minutes, perhaps?), which could be extended by delivering additional field supplies; it would have only a limited selection of non-perked vehicles (if a V-base) or fighters/light attack planes (if an airbase). There would be no radar for these bases. If something is destroyed, it only rebuilds if more field supplies are delivered. In the case of a v-base, it would have non-alterable spawn points in each cardinal direction, each limited to only a few miles.
Yes, none of this would be simple to add to the game. I just think it would add an interesting dynamic to the game. Flame away!
