Don't want to get too pointed here, but I'm thinking that some of the new gun vibration/shaking is way too severe is some instances. First, I'm not sure the a co-axial MG mounted fixed on a 40-50 ton tank would have any real shake to it, or for that matter the hull mounted MG either. The pintle gun, being a flex mount I can see.
The worst application of the gun shake is the Osti. We already had significant ballistic inaccuracy factored into the gun, now there is an extreme gun shake, again on a major tank chassis and what was essentially (I believe) some type windlass/crank mounting system. In any event, I don't think, the 37mm should have that much recoil effect.
From a strictly functional viewpoint, I haven't hit anything with it since the release and I had fairly good expertise prior and could hit 1 in every 6 or 7 planes I engaged. Certainly not up to Zazen's standards, but respectable and useful. Now it seems impossible to keep the gun anywhere near the target, especially diving aircraft, so we're pretty much at their mercy now.
I assume I'll get a little better with more practise, but it won't be targeting skill that will get better, just improved guesswork on spray n pray. If I'm correct, this could just about cripple the usage of the unit all together. Is this a bit of an over mod?
