The HTV, or Heavy Transport Vehicle, served the Imperial Army as a means of transporting replacement components and providing units with necessary supplies.
Each armor platoon received a complement of two HTVs. These vehicles were staffed by a crew of three (who also acted as mechanics) along with four extra technicians. Occasionally, the sergeant major would be detailed to this support group.
The headquarters (HQ) of armor battalions were equipped with 24 HTVs for transport, required to haul a significant quantity of droids (approximately 6 per vehicle), gear, and associated support staff.
