Stingray Mines are an anti-tank mine developed by Black Sun and makes use of an extreme pressure-activated firing switch (ensuring only a tank can set it off) and a C4 charge.
While an individual mine is respectable in terms of damage, stacking several mines in the same place can potentially outright destroy an enemy vehicle or block an enemies path. They can be prematurely detonated via Satellite Strikes, Grenades or the Scorchers flamethrower
While they can be effective, some vehicles are immune to direct damage by mines (The Dragonfly hovers over them, not setting them off) and the FLP-E can fly over them using its special ability. Unlike Auto Cannons, mines will detonate on any vehicles that passes over them- not being able to tell friend from foe.
