It's not the French, it's the cheap, light vehicles with massed MGs. The problem has always been here, the French just demonstrate it to the extreme. The 3rd AD with Stuarts and Halftrack could so something similar, but they don't have the income or cheap vet recon to make as effective.
This.
As an infantry player (lot of beloved 91.) i can tell you that vehicle MGs especially when they are grouped are nightmares. Infantry can't deal with it reliably if the vehicles are well used. So you need to buy more vehicles (With AP please, not everyone have a lot of them) to deal with those vehicles.
AT gun are nice, however costly, not as numerous as the half tracks/light vehicle hordes and wont survive very long with the proliferation of mortars, also how they are spotted easily.
The infantry wont do any shit to the half track/open top as long at it stay out of rocket launcher (If you ever have one) range even if the gunner stand still with half his body uncovered.
Then the tanks and vehicle fire all their MGs without any overheat or whatnot like in some Rambo scene.
Indeed, completely without impunity evaporating and pinning entire squads.
Funny enough my infantry cannot fire back at lightly armoured vehicles or shoot down the gunner. Even my own infantry HMGs can't.
Look like the soldiers back in 1944 were not trained to fire at such visible targets.
Also, firing out all vehicle MGs like crazy IRL would put your commander at risk and the gunner too busy to scan and be aware of the situation.
I do know i over-exaggerated it. Still for me its a valid issue.
I would wish the open top vehicle to get a crit "gunner knocked/killed" making them failing back when they are under fire. Add with this the ability to infantry HMG to fire back at lightly armoured vehicles, vehicles and open top vehicles inflicting the critical described earlier.
Maybe the infantry would be able to fire back at open top/half track when they are very close (150-200m ?), inflicting them the critical. It would be a good way to at least push them back (or maybe even surrender if they panic enough) when you have no infantry AT launcher or immediate AT gun/tank support in the vicinity.
Sorry about my bad English.
