And the reason that the current number of the Australasia Expeditionary Force is 16,000 is because the number of one division in Australasia happens to be 16,000.
Although the four major powers can easily gather a million troops together, just dealing with a small country like Argentina, let alone a million troops, a hundred thousand troops would be too large.
Even if all the troops had the strength of the Australasia regular army, Arthur is confident that he would only need 30,000 of them to conquer the whole of Argentina.
Although the troops sent by the four major powers are called the Allies Expeditionary Force, they do not all set off at the same time.
In order to arrive at the battlefield as quickly as possible, according to the internal agreement of the Allies, Australasia, which is closest to here, will send troops first.
The task of the Australasia Army is to go to Chile and help the Chilean army defend their territory.
