As tanks have gotten bigger and heavier, and become larger targets, there was an opening for smaller vehicles. Looks like a good alternative to an armored up Humvee.
Smaller, more expendable vehicles.
So make them remotely operated with vertical launch missiles ATGMs and MANPADs. Maybe another version with an automatic mortar, and another with an autocannon and automatic grenade launcher. And finally, some carriers for ammo and equipment.
Use them in numbers. Maybe one RPGV per platoon, or one of each type per company? That way you can have really heavy firepower with airborne or airmobile forces.
