Suggestion that was brought up by my friend and heavily inspired by construction system in DCS mainly used by utility vehicles and aircrafts
In a nutshell Tarantula will be able to "build" bases by delivering crates with materials, lets say 4 is needed when one Tarantula can carry only 2 of them
You wont be able to construct FARP near airbases and near some stuff that mission makers can restrict if they want
FOB itself will take some time to "construct" maybe 10 or more minutes, when its done it will be a spawn and rearm/refuel point for helis and some vtol's
Also, there would be an option to "upgrade FARP" to include more advanced weapon options, because regular FARP would have option to pick and rearm generic and "low tier" weapons (if that can be even implemented)
Repairing FARP would be simple as delivering materials again
