Had it removed because it seemed to me to be a pointless number that clutters up the stats. If you think you need it so much:

Argentina - 48,861 
Austria - 721,260 
Brazil - 274,455 
Qing - 11,589,240 
Colombia - 89,799 
CSA - 472,003 
France - 851,844 
Greece - 38,956 
Italy - 564,423 
Japan - 1,031,640 
Mexico - 263,930 
Netherlands - 486,921
Ottoman Empire - 778,547
Prussia - 803,314 
Romania - 98,773 
Russia - 1,959,205 
Spain - 572,307 
Sweden - 162,074 
UK - 5,427,226
USA - 1,055,122

These are the maximum numbers you can call up from your own country. It is impossible (and downright stupid) to try and call up this number in one turn, however.
