I use them as well to deliver supplies but the OP was about taking bases. I don't remember the last time a Jeep was used for that purpose, since a bike carries even less troops it will defiantly not be used.
It could may be used due to its small profile to sneak troops in if theirs a heavy battle going on for a town and theirs only 2-3 troops needed. Or even for patrolling for troops in a town, It would be a good troop hunter on the streets of town.
I held off 4 guys in EW by myself in a jeep one time using run&gun tactics on them. Hiding somewhere in town with a good view, shut engine off, listen for em, then once i know where they are, went after them.
Shot up 3 m3's and an sdk before they finally upped a t34 to hunt down my jeep
