After World War II, there was little money for defense spending
while the nations of Europe rebuilt their industry and society.
When there was some cash to spend, one had to be creative to
stretch it as far as possible. The French probably accomplished the
most astounding example of that with the ACMA Troupes Aeról Portées
Mle. 56. Deployed with their airborne forces, this was essentially
a militarized Vespa scooter outfitted with a 75mm recoilless rifle.
Five parachutes would carry the two-man gun crew, weapon,
ammunition, and two scooters safely to earth, and the men would
load the weapon on one scooter and the ammo on the other, then ride
away. More impressively, the recoilless rifle could be fired
effectively on the move by the best of the gun crews. Total cost?
About $500 for the scooter and the recoilless rifle was war
surplus. Were they successful military machines? Well, the French
Army deployed about 800 armed scooters in wars conducted in both
Algeria and Indochina."

Now the French paratrooper can boast of having a 75mm cannon
between his legs(while riding the scooter of course)!
