Mines - how best to use them.

[Soldier]

I tend to place anti armor mines on roads, to deny rapid movement to my opponent, etc. Also in clear narrow terrain, within otherwise impassable terrain to vehicles, etc.

My favorite place for anti personal mines, is in small patches of good cover terrain, enemy infantry tents to use to sneak up close to my defensive positions.
My hidden infantry and other support weapons (over watching such minefield/minefields) will hold their fire until enemy Inf unit stumbles into the said minefield and attempts to leave it into to open terrain around it, etc..
