yeah, thatd also be easy to simulate, you could give the mine clearer operator an action, check for mines, and for any mine within lets say 25 meters, a "danger" object would be camcreated, for ground engineers to disarm them, or for them to be blown up with a miclic.
and i do think its possible to give the plow a lot of health (note how the tank barrel can only take one hit, while the front armor can take 2 or 3 hits before being destroyed, if you gave the tank plow enuff armor value, its be indestructable, but would still get destroyed after a few mines (which is pretty realistic) the only prolem is that the mine plow would make the tank very indestructable to enemy tanks, but this shouldnt be a problem cuz youd never deploy a minesweeper ina combat zone...
