The M mm smoothbore mortar is one of the family of mortars developed to replace equivalent World War II-era weapons. The M benefits from US experience in the Vietnam War, which indicated the need for a reliable, lightweight weapon at the infantry company level. It can be fired from the standard baseplate and mount or handheld from a smaller baseplate. The mortar can weigh as little as 18 lb 8. The weapon can be either drop-fired or trigger-fired. But the gun was very unreliable. Several battalion commanders reported breakdowns of over half of the guns during missions; in one case, all 18 guns suffered failures during the same mission.

The United Kingdom's L16 81mm mortar is the standard mortar used by the British armed forces. It originated as a joint design by the UK and Canada. The version produced and used by Australia is named the F2 81mm Mortar , whilst the version used by the U. British army light role infantry battalions and the Royal Marines may transport their mortars in BvS 10 vehicles the replacement for the Bv The weapon can be man-packed by the mortar detachment, in which case the ammunition would be carried by other soldiers of the battalion. In addition to their normal equipment, each soldier would carry four bombs in a pair of two-bomb plastic containers known as greenies in the British Army.

The Geneva International Centre for Humanitarian Demining GICHD is an expert organisation working to reduce the impact of mines, cluster munitions and other explosive hazards in the world, in close partnership with states, the UN and other human security actors. Based at the Maison de la paix in Geneva, the GICHD employs around 55 staff from over 15 countries with unique expertise and knowledge. Our work is made possible by core contributions, project funding and in-kind support from more than 20 governments and organisations. Motivated by its strategic goal to improve human security and equipped with subject expertise in explosive hazards, the GICHD established a research project to characterise explosive weapons in January The aim of this research into explosive weapons characteristics and their immediate, destructive effects on humans and structures, is to help inform the ongoing discussions on EWIPA, intended to reduce harm to civilians.
The M multi-option fuze  is a rangefinder and collision detection system used on 60mm, 81mm, and mm mortar shells as a trigger to detonate the shells at the most damaging heights of burst when combating four types of battlefield threats:. This integration of four functions into a single fuze reduces the logistics and cost to support mortar crews on the battlefield. A typical mortar firing procedure is for a squad leader to select a target and call for one of the four fuze settings.
