Antipersonel mine
There are four categories of antipersonnel mines:

• Pressure/blast mines that injure by pressure from the blast alone.
• Fragmentation mines are mostly tripwire released and injure with metal splinters.
• Bounding fragmentation mines, which shoot upwards about one metre from the ground and blast metal splinters around 360 degrees.
• Directional fragmentation mines, which have a horizontal blast.

All antipersonnel mines are built to injure and maim adults. If a child detonates a device, the injuries are at best extremely crippling.

Antitankmine
Antitank mines are designed to explode if a vehicle or tank drives over them, typically requiring a pressure of 100 - 250 kg to activate. Antitank mines can easily be manipulated to blast with far less pressure such as a weight of a person.

Unexploded ordnance
Unexploded ordnance (UXO) can be anything from small hand grenades to missiles, and poses as great a threat as mines. Being visible and accessible on the ground is exactly the problem. Badly damaged and sometimes brightly coloured ammunition in the curious hands of a child can be enough to trigger an explosion.
