Why didn’t Australia use emus during WW2 as during the great emu war, they compare them to tanks and Merdith (the person in charge of the emu war) even says that "If we had a military division with the bullet carrying capacity of these birds they would take on any army in the world.
This seems stupid but the allies also tried to build a ship out of ice during WW2. So,using emus doesn’t seem so stupid. So why didn’t Australia try it?
There are simply no stupid questions, merely stupid answers so thanks you for this, quite fun, topic 
Actually, in hindsight not so fun for all the animals…I must add.
Animals were used and abused by the thousands…horses still were the main tork on German and many other army’s to get from a to b with heavy equipment, in contrast of what many presume.
The Soviets used dogs, provided with a landmine to go and lay under panzers and all sides used many pigeons as runners for messages. Also in mountainous areas mules were much used…so, again, your question is quite valid
Apparently the EMU was to protect the crops in Western Australia but the Emus were great at evading and Western Australia is one if not the most remote area in the World. The coloured Cassowary is a lot meaner by the way, the Emus just use their long necks to steal any food they think you carry.
Also Australian army lost the Great Emu War of 1932 and the peace treaty forbid of any wartime use of emus thereafter. Enlisting any emus to any job in the military would have been a violation of the treaty and caused a Second Emu War which Australia could ill afford.
True, the Australians also ran the risk that the drop bears would team up with the Emu’s. No one is stupid enough to start a war with the famous drop bears. ( I have just over 2 hours left to write these posts:crazy_face:
)
The Australians were not too happy about the results of the Emu War, so you could understand how there was bad blood between the previous warring factions
So to sum up, emus lie in Western Australia which is pretty remote, so the aussies won’t bother going there. And there was bad blood ( 
) between the two, so they wouldn’t team up?
