perhaps it should be considered that the DUKW is not a beach assualt craft .. your engineers would do better landing in landing craft ..DUKW were used in unopposed landings like when they went directly from Sicily to the Italian Mainland in 43 ..but that was a bit of an exception ... they would be bringing supplies from ships to and onto the beach as the landing developed . but not in the assualt wave , somewhere i read the primary cargo for the first wave of DUKW's would be the 105mm towed .. i can't remember the source ... and typically they would be occupied bring supplies in from ships until docks could be secured ..then they would more or less enter the general motorpool as either transport or a supply carriers ..
smoke the beach come in with engineers and funnies in landing craft ..if you bombard the beach it will remove and spot mines ..at least in pre 5.0 versions..won't clear a lot of mines but i think engineers are less likely to take casualties from spotted mines ..at least that has been my experience and if you smoke the minefield so the engineers can't suffer direct fire you may survive long enought to clear a lane
Sometimes it is a matter of asking units to do what they were never expected to do ..and sometimes there is no good way for them to do it without unacceptable casualties
