Suitcase of mines: New US aid to Ukraine features M131 MOPMS
The new military aid package for Ukraine includes an unusual weapon: the Pentagon has confirmed the delivery of the M131 MOPMS system. This system is essentially a self-deploying minefield contained within a suitcase. We explain how this equipment functions.
In addition to artillery, mines are among the most effective types of weaponry used during the conflict in Ukraine. The new tranche of American aid includes equipment that facilitates the remote creation of minefields.
The Pentagon has agreed to deliver M692/M731 ADAM artillery ammunition, which allows for remote mining, the mobile M136 Volcano mine-laying system, similar in operation to the Polish Baobab-K system, and the portable M131 MOPMS set, which enables the remote creation of a minefield.
While remote mining with artillery is not unusual, nor are mobile remote mining systems, the M131 MOPMS set is distinctive due to its operational method and its unique form.
M131 MOPMS – a suitcase with a minefield
The M131 MOPMS (Modular Pack Mine System) is a complete remote mine-laying system contained within a container weighing about 55 kg, resembling a suitcase and equipped with retractable transport handles, allowing easy carrying by soldiers. Inside, apart from the control system, there are 21 anti-personnel and anti-tank mines.
Creating a minefield barrier involves placing the "suitcase" on the ground and remotely initiating the deployment of mines, which are scattered around the container. Two minutes after deployment, the fuzes activate, creating a minefield measuring approximately 35 by 70 metres, ready for operation.
Thus, after deploying the M131 MOPMS containers in advance, a minefield with a specific mode of operation can be created and activated swiftly. The mines may detonate upon contact or with a delay. Additionally, they are equipped with a self-destruct mechanism, ensuring they pose no threat after the end of hostilities.
