The names are for the most part what various armies call them, in some cases it may show that they are considered more of an elite unit with a pioneer designation or more combat/assault orientated. For mineclearing purposes keeping them under cover and unsuppressed is going to get you the best results. As for detection that tends to be the job of scouts and or patrols although attaching a engineer/poineer squad to these units doesn't hurt.
