The M1, M1A1 and M4 are circular steel cased United States anti-tank blast mines with a distinctive cross shaped pressure spider. The mine was used during the Second World War and a copy produced in Argentina was used during the Falklands War. Another copy is produced in China, there designated as the No. 4 mine.

The metallic Anti-Tank Mine M1A1 has three main components: loaded body, fuze, and spider. The spider fits over the fuze to increase the effective size of its head. The steel body is a squat cylindrical container of light steel filled with high explosive. A carrying ring is attached to its side.

The M1 was a United States chemical landmine. It was developed in 1939, and consisted of a one gallon (4.5 liter) gasoline can filled with 9.9 lbs (4.5 kg) of mustard gas agent. As issued, it had no bursting charge or fuze, but required a bursting charge of detonating cord to be attached via soldered tabs on the outside of the can. [1] [2]

The M1 Mine is a US World War II Anti-tank mine, there were basically 2 different versions, the M1 and M1A1 which were very similar. The M1 was the initial variant but it was prone to unintended detonation due to its fuze construction while transportation.

The M1 anti-tank mine consists of a circular base containing the explosive (2.75 kg of TNT) surmounted by a cruciform pressure plate. The detonator reacts to different pressures: a lateral pressure must reach 120 kg while a central pressure must reach 250 kg.

Features: The Mine Clearing Blade System for the M1A1 Main Battle Tank is an ancillary piece of support equipment. It is electrically operated and is capable of clearing surface or buried mines up to 6 feet in front of the tank's path without the aid of supporting forces or additional equipment.

The US M1 1-gallon chemical landmine is a stark reminder of the devastating potential of chemical warfare. Developed in 1939, it combined simple design with lethal effectiveness, capable of contaminating large areas with mustard gas.

The M1 was a mine that was used by the United States during World War II. It had a total weight of 4.9 kg and a 203mm diameter. Since it was designed as an anti-tank mine, it required a minimum weight of 120 kg on top of the ring fuse in order for the shear pin to be broken, releasing the striker into the activating mechanism.

Features: The M1A1 is an improved version of the M1 Main Battle Tank (MBT). It includes a 120mm smoothbore main gun, an NBC overpressure protection system, and an improved armor package. This tank significantly increases the capabilities of the Fleet Marine Forces across the full spectrum of conflict in the near and midterm.
