Ammunition & Resupply Vehicles

Ammunition & Resupply Vehicles: The HIMAR consists of a resupply system that provides ammunition and fuel for the crew. The HIMAR comprises six vehicles: ammunition, a fuel truck, a support vehicle, an engine technician’s vehicle, a mechanic’s truck, and a maintenance support vehicle.
The ammunition platoon has hundreds of rounds of ready-to-fire artillery shells. It has 180 rounds per minute delivery capability with at least 4 vehicles per battery available for manufacturing continuous production. Each vehicle is equipped with a cargo bay capable of carrying 4 artillery rounds.
The resupply platoon supplies and maintains all items required by the battery and crewmen to accomplish their duty.…work area is the six Resupply Trucks used by each troop. The Resupply Trucks carry an inventory of spare parts for all M270 systems and equipment used by the troop…
The fuel platoon provides fuel to other elements within its battery or company. Fuel is transported from the fuel platoon to other elements utilizing HEMTTs (Tanks). These tanks can be filled up at Fuel Points anywhere behind front-line positions.
The engine platoon provides engineer support to the battery. These vehicles are equipped with a winch designed to pull artillery tubes, dump trailers with equipment or parts, or pull the gun if it is disabled. They also have an excavator capable of removing obstacles.
The maintenance platoon supports all elements of the battery by providing repairs and maintenance of the M270 System. The Maintenance Vehicle is used for transportation between the battery, resupply point, and rear area servicing points. It also provides personnel for personnel recovery duties.
The support platoon provides office and supplies support to the battery. The vehicles contain the battery’s office equipment, computer systems, storage areas for personal equipment and supplies, and other non-powered vehicles.
MLRS Tests

The MLRS is a rocket system capable of launching rockets over long distances.MLRS crew members are in charge of the different components that make up the weapon, with two people responsible for each rocket that leaves the launcher. These operators are responsible for performing equipment checks to ensure safety, use of targeting devices to line up target locations and operating all systems on their assigned launcher. Crew members have an important role in this branch of support because they serve as both artillery-spotting personnel and air defense artillery-spotters by day, firing rockets at targets designated by other units.
Radio Communications

This is the practice of communicating over a distance by electromagnetic waves. The Radio Operator is responsible for all communications equipment, including but not limited to the ground-to-air radio, air-to-ground radio, Airborne Radio, H.F. station radios, or antennae.
Radiofrequency spectrum allocations are divided into three bands: Low Frequency (L.F.), Medium Frequency (M.F.), and High Frequency Bandwidths (H.F.). These frequencies are designated by their wavelength. The transmitter modulates the carrier wave with audible sound waves called modulation. Modulation is done by either AM (Amplitude Modulation) or F.M. (Frequency Modulation).
The primary purpose of the radio operator is to maintain support between HIMARS units and adjacent units. The operator will receive, process, and relay all friendly fire orders that are directed to him. He will also relay all enemy fire orders directed his way that he deems relevant.
The operator must have the ability to monitor communications over the battalion net, company net, platoon net, and forward observer nets to include both line-of-sight and beyond the line-of-sight capabilities. The operator must be able to maintain contact with all friendly units through organizational lines or higher headquarters.
The operator must be able to identify the threat level of the enemy by distinguishing between muzzle blasts and real ordnance. He must also be able to tell if rounds are falling near or on his unit through the detection of time distortion. This helps determine if the enemy fire is falling short or overshooting.
