The government used US supplied land mines to protect bases and installations against insurgent attack. The insurgents (FMLN) used mostly home made land mines to deny the Army access to there operational areas.

As the Army became more effective with US training and support, the insurgents used land mines to attack the military.
Mines were the scourge of the Vietnam War. It seemed like everyone and everything was hitting them. Grunts where stepping on "bouncing Bettys", tanks were running over Soviet supplied anti-tank mines, and the US Navy's Swift Boats were getting blasted out of the rivers by floating mines. Land mines, riverine mines, and booby traps (un-conventional type and/or placement) were the bane of the Vietnam war. Once you or your tank hit one, "you got mined."
The torpedoes of the US Civil War were water mines that were designed to explode when a Union ship happened to hit one of them. Later, the Confederates developed mines that could be set off from a river shore via a electric wire.
