M30 Signal Corps general repair truck
Not all signal corps vehicles were assigned a K number, some were assigned Ordnance numbers since they were just a variation of the CCKW repair van, officially called the Shop Truck ST-5 van body and ST-6 van body. It came in two versions, the M30 and M31.
- M30 has isolated shock mount shelves for delicate equipment, 6 to 24VDC battery charger, air compressor, and more outlets and plug-ins to allow multiple units to be simultaneously tested.
- M31 Has two repair benches for communications equipment. Includes hand and power tools and bench grinder. No generator provided.
Both had the ST-5 van body in common
