Are there logistics? And if so I hope they pay less than troop transportation

Reason I ask is if you’ve ever played arma you’d know in most servers the majority of people operating vehicles are not doing it to bring troops to front lines, they only get genuine “xp” for bringing supplies to the front line or FOB’s.

My frustration with that system is that if transporting one or the other type of cargo gives more money or xp you’ll either have troops and FOBS under supplied or a ton or frustrated troops having to leg it to the combat zone.

Any of the peeps who’ve already played know how it works?
