IMPORTANT NOTE #1: The infantry airborne formations are designed to use the S.M.75 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 Marsupiale 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 Marsupiale can carry 40.  The S.M.82 Canguru is the only transport that can carry the anti-tank gun in airborne operations.*
*
IMPORTANT NOTE #2: This formation uses the Unit Class "Airborne Field Howitzer" for the airborne anti-tank guns, as there is no "Airborne Anti-Tank Gun" class.  This was done to separate this particular anti-tank gun from all the other anti-tank guns available, as this was the only gun used in the airborne role by the Italians in this time period.*
*
Because the anti-tank gun uses a howitzer gun class it will appear in the Bombardment Plotting Screen.  This gun was often utilized for anti-personnel and indirect fire, so it is appropriate to also use this gun from the Bombardment Plotting Screen.  It will also be able to function normally as an anti-tank gun without any penalties.*
