Landmine

"But you didn't even bury them."

- Grif about the mines

"From what I can tell, they're designed to rest above the ground."

- Simmons

"With big red warning lights?"

- Grif

"Yeah, it doesn't really make sense."

- Simmons in Ready…Aim…

A Landmine is a explosive placed on the ground and detonates when enough force is applied to it. They first appear in Ready…Aim…, where Simmons makes a minefield when the Reds and Blues are fortifying Crash Site Bravo for the upcoming attack of the Federal Army of Chorus.
