Nonsense. You talk as if the IG18 will hit with every shot that is just bullocks. just like the mortar the support gun is useful in displacing and weakening mg's and enemy mortars but do not expect it to kill a well microed mg.
automatic weapons greatly benefit from vehicle size allowing all their shots to hit so no idea where that comes from.
And FSJ are doctrine dependant and its utter bullocks to even suggest as a counter and second not every map has building. also its a one time affair. now stop posting your just embarrassing yourself.
Well ISG hits 99% of the time and if you have a Sturm officer nearby it will never stop shooting. It will shoot as fast as a zis shoots its barrages.
