I have...just so many questions about that Vespa.
How does one reload the gun after firing?
Would the weight of the Vespa and the rider be enough to counter-act the recoil of the gun?
How slow is it? Because judging by the fact that my little brother's scooter barely does 60mph and is only a couple CC's below being an actual motorbike, I can't imagine this thing doing more. Especially since it's got small Artilery piece, plus ammo, built into it.
Why would you even need such a thing? It's basically a small-caliber, unarmoured tank-destroyer that has to be manualy shoved around to aim, isn't it?
Would you use your crotch as an improvised cross-hair? Since by the look of it, it is a litteral crotch rocket.
I know the French used something similar during the conflict in French Indo-China (Present day Vietnam, I think), but that was because it was easier to do that than lug a full blown artilery piece through the jungle.
Did the Italians use it in a similar role, or were they working on the rule of cool and use these things in open combat?
