What did Italy use to fight in World War 2?

Answer 1

I assume you're asking what weapons Italy fought with during WWII.

Italy, like most other countries at the time saw the rapid mobilisation of armoured warfare throughout the war. Italy's campaign in Northern Africa was mainly based on tanks and other armour.

In addition to heavy-scale armoured warfare, Italy had also introduced an Air Force by 1939. This resulted in Italy attaining planes and fighters to engage in aerial combat.

Italy used a variety of weapons and tools during WWII, they weren't too different from what other countries were using, just think of the usual, Ships (although Italy, during WWII had a VERY pitiful Navy, and was wiped out by the British very quickly), tanks, guns, artillery, planes and such.
