FUFO , 255-300G hardness and a parachute for the strategic yield option of the ingame B61 clone.

well the GPO-N is not a B-61, and its reasonable to assume that 250kt is its max yield, as nuke yields have been trending downwards for a while.
about spaag shooting your bomb on the ground, hust kill the spaag first, this is a balancing measure.

So only the spaag can shoot my precious munition on the ground. I'll pick them off with cruise missiles first.

...what makes you think it's unrealistic for AA that can hit missiles moving at Mach Jesus to swing the turret around and hit a stationary ground target?

[gleaming ferry]

Go outside of the city , open Google earth , measure 2-3 miles away from you and imagine something the height of your room and diameter smaller than your toilet laying somwhere , obscured by vegetation , angle etc. ..

[manic prawn]

OK, but my eyeball doesn't have the Mk.27 Prostate Finder optical tracking system that can put a cannon on target against a maneuvering target at the speed of sound without the use of radar

...less laconically, the SPAAG knows where the bomb is, because it saw it fall in a predictable manner, and now only needs to fire where it knows it is.

[gleaming ferry]

It's a game thing, in reality due to the angle you wont see or hit it. Prostate finder , Holly crap is that a new type of an exiting toy..

Wont see or hit it unless you are on the rooftop of a very tall building or upslope on a mountain, and then there is vegetation and soil penetration , gliding etc...

That's not true first of all - automatic tracking is extremely good in currentyear already - but importantly, in the NO context it only needs to be seen by something, even a shitty little LCV somewhere, because of the universal datalink
