Mine Clearing

Mine clearing is one of the most nerve-wracking tasks for an engineer. Engineers must be supported by friendly forces in order to have a chance of clearing a path through a minefield or similar. The minesweeper tool that engineers have is capable of detecting mines out to about ten meters, and depending on the difficulty setting of Arma, you may get a visual indication when one has been detected and where it is. Without the indicator, you’ll need to scan for them visually - a time- consuming process, even more so when in thick grass or otherwise cluttered terrain.


Spacing between engineers is extremely important when mineclearing. If a lane is being created - the engineers need to space themselves sufficiently to clear the lane thoroughly, without risking all of them being killed by a mine detonation. Non-engineers stay sufficiently far back as to not be at risk of being caught in a mine blast.

  1. Once you’ve identified a mine, go prone and slowly crawl towards it to avoid triggering the fusing method.
  2. Your toolkit will allow you to defuse it.
  3. Once defused, you can place it in your rucksack or leave it there.


A defused mine sits atop the ground, visually distinct from an emplaced mine, but you’ll have a hard time convincing a tank driver of that. When possible, a trailing engineer should remove defused mines and stash them in a different location while the main minesweeper continues his work. The trailing engineer should place lane markers if available - at night, these can take the form of chemlights. These lane markers give follow-on forces a clear visual guide of where safe passage can be found.


In the event that toolkits are not available for mine clearing, most mines can be defeated by firing at them. It is of course recommended that all friendly units clear out of the area before attempting this technique. Note that most mines are blast- hardened - if you destroy one and cause it to detonate, nearby mines will not detonate because of that (known as “sympathetic detonation”). Grass and other vegetation, as well as the undulation of the terrain, can make it very difficult to spot and hit mines from a distance with gunfire.

Generally speaking, grenades and other explosives will be insufficient to destroy mines remotely. The one exception to this is a mine-clearing line charge - something which you may see in an Arma 3 mod. These are rockets with large chains of explosive attached to them that can be fired into a minefield and then detonated, clearing a small path through it. Aside from such line charges, do not assume that your explosives will be effective at clearing out mines. 


Some examples of buried mines follow for familiarization purposes.
