I'm not talking about MG spam.
Omega_Warrior, in the example I gave, the MG42 was already deployed and began shooting at the Maxim before it was even set up, then ended up losing.
Well Without seeing it I can't fully say for sure why this would happen. There are plenty of other variables, such as cover. If the maxim was in yellow or green cover and the MG42 was in neutral or red, the MG42 might have not been able to suppress the maxim with one salvo which would give the Maxim time to set up and fire back.
The MG42 could have been halfway through it's salvo already or needed to reload. If they Maxim appeared on the edge of the MG42's arc it would have also taken the MG42 a second to turn the gun. There is so many variables I couldn't say for sure just with a loose explanation.
