No kidding, even if you are drunk enough not focusing fire on the Pio, the S-mine just planted by Pio would be triggered by one cons model and the Pio will be ripped into pieces.
One advantage of S-mine fast planting time is, used to plant at opponents retreat route and wipe out his retreating half dead squad. Best to use against shocks, guards and snipers.
That's nonsense sorry. The build time is like 1 second so you can't focus fire them and also small arms do not trigger mines and the Pio can simply retreat after finishing one part of the minefield. It's funny how ALL of your posts are PRO Ostheer and your stats show that you almost exclusively play OH.
