Any amount of smoke, or light vehicles, are enough to fight against MG42s early game. Every allied faction has access to one or both of these tools early on.
As are flanks, which can indeed be done against Ostheer MG42s, most 1v1 maps provide plenty of sight blockers and alternate routes to get around strong MG positions.
This MG will instantly supress multiple units in just one burst and the recovery time is LOOOONG. When you smoke an MG your units will be pinned and by the time they recover the smoke will have cleared in time for them to get pinned again.
