Hi there, some of the Russian lists allow "Penal Troops - Mine Clearing" but I can't see anywhere in the rules (or on the forum) detailing how these work to clear mines.  Thanks for the help.

Probably you walk them forward until they get to the other side of the minefield.
If they're lucky

That's exactly what you do 

You dice for the effect of the mines for each 5cm they advance through the minefield.
For each 5cm they move they effectively clear the mines. If they are KO'd they path they have cleared remains cleared behind them. So you will, in effect, always get 5cm of cleared minefield regardless of whether the unit is KO'd immediately or not. The unit can be suppressed just the same as any other units.

Cheers

Great thanks
