Land mines became a very useful weapon in that sort of war because land mines are a weapon in which you can control people. You can control movement. They're usually used as a defensive weapon, but you can also seal off certain areas and keep yourself protected and keep communities from leaving because you want to control those communities.
Land mines are insidious weapons.
When you aim an AK-47 or a piece of artillery, you know what you are aiming at. But a land mine is different. It is not removed. It can become a menace for years and decades ahead. Mines don't distinguish between a footfall of a soldier or a woman collecting firewood or a child taking livestock into a field.
