IMPORTANT NOTE: The infantry airborne formations are designed to use the S.M.75 Marsupiale and its 20 troop capacity.  The mortar and anti-tank gun paratroop formations are designed to use the S.M. 82 Canguru.*  The S.M. 75 Marsupiale was specifically outfitted to carry paratroops, and was the transport of choice for the Italian airborne from 1940 on.  The S.M. 82 Canguru had a much wider and deeper cargo area, and so was utilized to carry heavier loads.*
*
The Caproni 133T and the Savoia Marchetti S.M.75 have half the carrying capacity of the Savoia Marchetti S.M.82.  The Caproni & the S.M.75 can carry 20 troops, while the S.M.82 Canguru can carry 40.  The S.M.82 Canguru is the only transport that can carry the anti-tank gun.*
