I want CEs and Pios to suicide themselves clearing mines if I want them too not just sit there and shoot back if there is a single enemy near leaving the mine field for me to have to deal with later.
Thats my biggest gripe about sweepers. Put down your rifles already and clear them SMines already....
I'm 90% sure you can clear mines while under fire. If you let your engineers sit around the mine they will defuse it until they spot an enemy, same with attack move. But if you actively select the mine they should defuse it.
