In Combat Arms, to mine stack, you need to place multiple mines in close proximity to each other, ensuring they are positioned effectively for maximum damage. First, deploy your mines in strategic locations where you anticipate enemy movement. Then, use a combination of different types of mines, like anti-personnel and anti-vehicle, to increase your chances of catching opponents off guard. Always be mindful of your surroundings and avoid placing mines too close to friendly players to prevent accidental damage.

The Confederates used two types of mines, they were either self acting ones or ones controlled as Samuel Colt had experimented with. The self acting mines exploded on contact when a vessels hull came into contact with it. The controlled mines were set off from shore by a concealed observer. When a targeted Union vessel came close to the mine's location, a switch was clicked on and the mine exploded. Most of the Confederate mines were of the self acting types.
