>>25955I mean it really wasn't –that– over-the-top. Let's consider for a moment that Hannibal recruited something to the effect of 30-50k native tribesmen just from Italy alone, not including actual Italians or obviously Romans. The Romans lost 70k in Cannae, 30k at Trebia, and something like 100k in assorted other battles but were still ready to keep raising legions. This doesn't take into account the truly massive armies of Persia and China during the same time period.
If we take for granted the fact that the Empire is obviously not!Rome, with the added benefit of D&D style magic that breaks economies in half around the time you get to Fluder' level, the idea of having 120k troops on the field isn't a huge deal, it's Cannae plus the legions they lost at Trebia. Remember too that the Empire has been in a state of "war" for a number of years yet has lost minimal numbers to conflicts simply because their fights aren't real fights.
On the Kingdom side, yes, 300k peasants is pretty ridiculous for a country whose basic premise is based on medieval France crossed with the HRE - but that's just the thing, it's presented as stupid and overblown, ridiculously oversized and not at all intelligent on a government level (though I'm not sure about in the anime).
