2 shrek squads will easily take out a vickers from the front (assuming no shrek dance). For every squad of infantry a Brit player has + officers, the Wehr player can make an MG42 and a squad almost. Brits can only concentrate their entire force in one are to force a breakthrough otherwise they'd never get through those defenses. Wehr can do small hit and runs and there's nothing the immobile emplacements can do about it.
Also, the vickers cone of fire doesn't matter if you have one squad holding its fire while the rest seep through.
