(Its mine field)
Using hand grenades or other means like a law from far away and oh yeah don't forget the M203 launchers, can be effective. I haven't seen many minefields in OFP and the real threat is mainly one or two or three mines put across the road by engineers or black ops.
What kind of AI are we stopping? If its tanks there is not much that can be done since they aren''t the best vehicles to have perihpial vision in. Try the CWC campaign mission "Rolling Thunder" where you have to capture Montinac with your tanks and attack the heavily defended road area in the middle of your route. I thought I was bad ass unitil 2 tanks including mine were out of action and the other two trapped with out turrets casue the turret was badly damaged and then the infantry had AT3's, not pretty. Not to mention my tank was upside down.
Tanks need infantry in front to find the mines first then they can avoid them.
