And the above can as likely wipe the 4 man squad. Loosing 3 men on a MG42 and forcing a retreat is a worse situation than losing 3 men with a maxim and forcing a retreat. If a model dies on the retreating maxim, it might get stuck in the deathloop and the unit may die. If a model dies on the retreating MG42, the unit will die.
If you loose 3 models in a single strike thats rng or the crew is clumped up. So yes bad for any mg.
The maxim is naded frontaly the most out of any mg by a single squad. Because it cant supress in time often enough to stop them throwing the nade.
A problem wich both mg42 and 34 do not have vs a single squad wich attacks frontaly ever.
The added fact of the deathloop means even with 6 models who will most likely drop like flies after the nade do not have a teleporting mg to the surving squad members once they move or retreat.
If the gunner is killed during moving or retreat the deathloop will start when he dies period. Its just a matter of having it attacked by any inf or vehicle with mg,s to keep the gunner dying trying to pick up the gun. Wich is not much effort at all.
The mg42/34 do have a teleporting mg and thus will escape where the maxim will get wiped.
These 2 facts alone mean that even with 6 men the maxim is the most wiped and most easely wiped of any mg.
People who claim otherwise need to come back down to earth.
