Apparently not. Engineers "mark" mines but don't seem to de-fuse them during CM battles. Mines don't always detonate, though. Sometimes a vehicle can pass through a minefield unscathed. That seems to be by pure dumb luck.
Here's what the CMBN manual says.
CMBN Manual - page 57
MARK MINES
This command enables engineer units to detect and mark hidden minefields so that other units are aware of them. Other units can then move through the marked minefield, albeit slowly. Mark Mines is a very slow movement command that takes the unit’s full attention and reduces awareness and returning fire. See the Encyclopedia chapter for more details about Mines.
Restrictions - only Engineers can mark mines.
Example - Marking mines under fire is suicidal unless you have other forces suppressing the enemy or call for a large scale smoke screen.
CMBN Manual - page 195
MINES
There are three “flavors†of minefields in the game: anti-personnel, anti-tank, and mixed (meaning: a mix of both anti-personnel and anti-tank mines in the same field). Obviously, anti-personnel mines are meant to harm infantry primarily, while anti-tank mines are usually bigger and pack more punch, and are intended to disable or at least immobilize vehicles and tanks.
Note: Anti-tank mines cannot be set off by infantry on foot, but anti-personnel mines can be set off by vehicles.
Troops moving through minefields have some ability to notice the mines without exploding them. This is much more likely when:
.......................................... - The soldiers are crawling or walking (and to a lesser extent, “huntingâ€)
.......................................... - The soldiers are engineers
.......................................... - The soldiers are experienced
.......................................... - The minefield has already been discovered (e.g. by setting off a mine)
Engineers have the ability to mark known minefields. After a minefield is marked by an engineer unit, other units may safely (but slowly) move through it without running the risk of setting off additional mines. See the Mark Mines command in the Command chapter for more details.
