That's not all, a second (conflicting) upgrade will be available for you to upgrade the Technical too (instead of the Transport).
You can upgrade a Technical to a Car Bomb, this will pack it with explosives in the trunk, but still keep the passenger seat for transport (engineer caps a building in the chaos for example).
Keep in mind the upgrades conflict, its either a Transport, a Car bomb, or leave it as a fast recon vehicle.
