Bounding mine in the context of High explosive

A land mine, or landmine, is an explosive weapon often concealed under or camouflaged on the ground, and designed to destroy or disable enemy targets as they pass over or near it. Land mines are divided into two types: anti-tank mines, which are designed to disable tanks or other vehicles; and anti-personnel mines, designed to injure or kill people.

Land mines are typically pressure activated, exploding automatically when stepped on by a person or driven over by a vehicle, though alternative detonation mechanisms are sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Land mines are typically laid throughout an area, creating a minefield which is dangerous to cross.

Valmara 69 or V-69 is an Italian bounding anti-personnel mine manufactured by Valsella. The mine was developed from the V-59 mine, and although the mine is no longer produced in Italy, a number of copies were produced in other countries e.g. the all-plastic anti-metal detection "SPM-1" manufactured by Singapore.

The South African version was called the J-69, and was an identical copy of the Italian version. A single centre prong version was also produced. It is no longer produced by South Africa who are compliant with the Mine Ban Treaty requirements.

An anti-personnel mine or anti-personnel landmine (APL) is a form of mine designed for use against humans, as opposed to an anti-tank mine, which target vehicles. APLs are classified into: blast mines and fragmentation mines; the latter may or may not be a bounding mine.

APLs are often designed to injure and maim, not kill, their victims to overwhelm the logistical (mostly medical) support system of enemy forces that encounter them. Some types of APLs can also damage the tracks on armoured vehicles or the tires of wheeled vehicles.

The German S-mine (Schrapnellmine, Springmine or Splittermine in German), known by enemy Allied Forces as the "Bouncing Betty" on the Western Front and "frog-mine" on the Eastern Front, is the best-known version of a class of mines known as bounding mines. When triggered, these mines are launched into the air and then detonated at about one metre (3 ft) from the ground. The explosion projects a lethal spray of shrapnel in all directions. The S-mine was an anti-personnel mine developed by Germany in the 1930s and used extensively by German forces during World War II. It was designed to be used in open areas against unshielded infantry. Two versions were produced, designated by the year of their first production: the SMi-35 and SMi-44. There are only minor differences between the two models.

The S-mine entered production in 1935 and served as a key part of the defensive strategy of the Wehrmacht. Until production ceased in 1945, Germany produced over 1.93 million S-mines. These mines inflicted heavy casualties and slowed, or even repelled, drives into German-held territory throughout the war. The design was lethal, successful, and often imitated.
