Italy can't be added because they had the worst military in WW2. They used mostly old German weapons, vehicles and etc and most Italian soldiers would rather retreat from a fight, than actually fight the battle. Even Japan had better tanks, weapons and soldiers than Italy, and Japan wasn't even recognised for their Army, but rather for their astounding Navy, artillery and Air Force.
Italy won't be added and you can quote me on that.
You seem unwilling - or unable -to differentiate between realism and authenticity. (and also,you are unhistorical). Normally , I am unwilling to engage like this,frankly, bcs if I debate, I do not want my opponent to argue that I hide behind my badge,, or whatever nonsense. But, there is so much wrong here, again,that I feel I have to take off my staff hat and help you. Therefore, if you wish to resist stubbornly but politely, sobeit. Other staff can moderate us, for as long as I can be bothered to stay in the discussion.
Italy did not initially have the worst military in WWII in the way you describe: quite arguably, that description might have fallen on the French or the British in May 1940. I don't mean in just equipment - but outdated thinking, when facing the re-energised Wehrmacht. The French and the British had large armies, but their Commanders' mindset was apparently stuck in WWI (in no small means, through the drastic demobilisation after WW1)
Italy had made its own gains in East Africa - and it took people like Slim and Wingate to dislodge them -and they were effective operators,as the history of the British 14th army confirms.
Japan wasn't even recognised for their Army,
Oh please: this is what I mean by being unhistorical.
At a simplistic level, watch for the n
th time "the Bridge over the River Kwai" - it gives you a taste - only a taste- of how the Allied armies had to reinvent themselves, by jungle training. Or you might watch "Merrills Marauders" - again only a taste, of how an US task force operated in the Burmese jungle.
But however you see it from Western eyes, there is little doubt (in my mind) that the Japanese Imperial Army was a formidable foe for the Allies whom they faced: the Japanese were committed 100% (Bushido) - and you ignored their soldiers at your peril. e.g.the Phillippines; Singapore; Borneo; Indonesia; The French East Indies (Vietnam); Burma; Guadacanal; New Guinea; the Solomon islands; Saipan; Tarawa; Iwo Jima; Okinawa...
