Certainly gives one pause to consider such vehicles as the M108/M109 as a platform for such a system if there is sufficient space in the hull for the turret to fit.
Thanks guys ! actually the turret ring of the M-108/109 is larger than needed for this so a filler would be needed in 1:1 scale too.
Totally plausible. I could see these being used in Lebanon during the worst of the urban battles. Yeah, 35mm's a little heavy for street-sweeping, but the IDF have always liked big hammers.
