The M40 recoilless rifle is a portable, crew-served 105 mm recoilless rifle made in the United States. Intended primarily as an anti-tank weapon, it could also be employed in an antipersonnel role with the use of an antipersonnel-tracer flechette round. This is part of the military displays at the National Guard Militia Museum of New Jersey in Lawrenceville, New Jersey.

Take a look at the inside of the National Guard Militia Museum:

The bore was commonly described as being 106 mm caliber but is in fact 105 mm; the 106 mm designation was intended to prevent confusion with incompatible 105 mm ammunition from the failed M27.

The air-cooled, breech-loaded, single-shot rifle fired fixed ammunition and was used primarily from a wheeled ground mount. It was designed for direct firing only, and sighting equipment for this purpose was furnished with each weapon, including an affixed spotting rifle.

The M40 is shaped like a long tube with an M8C .50 cal spotting rifle above. The spotting rifle fires a round whose trajectory closely matches that of the 105 mm round and gives off a puff of smoke on impact with the target.

Manufactured by Kaiser Jeep Corporation, The U.S. Military M274 Truck, Platform, Utility, 1⁄2 Ton, 4X4 or "Carrier, Light Weapons, Infantry, 1⁄2 ton, 4x4", also known as the "Mule", "Military Mule", or "Mechanical Mule", is a 4-wheel drive, gasoline-powered truck/tractor type vehicle that can carry up to 1⁄2 short tons off-road. It was introduced in 1956 and used until the 1980s.

This example is missing its driver’s seat.

The M274 Mules were often outfitted with a wide array of weaponry, especially in the Vietnam War. They could be modified to carry virtually any type of conventional weapon that could be mounted on a truck.

The display is part of the National Guard Militia Museum of New Jersey in Lawrenceville, New Jersey.

The museum displays small arms and other weapons, uniforms, flags, medals and personal equipment dating back to the Revolutionary War.

The museum depicts over 300 years of New Jersey's military history and tells the story of New Jersey's citizen soldiers.
