According to official MH info from books and more yes countrys in MH have militarys and there has been wars.

Its said in one of the books that the ancients that built the tower and more died out from a war with Dragon Technolagy(Dragon element shots and weapons along with equipment such as rust weapons, ancient armors(Like in MHP3rd), the Kirin LBG, Fatalis equipment and more is all products of ancient Dragon Technology left behind after a war to stop its evil creators who was killing of creatures to the point of neer extinction.

So yeah that very much says wars happen in MH but the Hunters Guild now prevents over hunting that was said to start the ancient one.

About Schrade Castle I beleive it was actually Fatalis that finished off that place if it was war that killed it because last I heard "So complete is the devastation, that no one remains to mourn its passin."(MHFU info magazine) so yeah its true Verudo and Liber city are now the capitals of the Scrade Region one is a Republic other is a Kingdom.

Also I recall somewere it was said hunters get considered Elite status in the military as the countrys first defense. But I doubt all of them wish to be involved in Human VS Human war situations.

So in a way the Hunters Guild and the Militarys work together depending on situations.
