Could you be more specific.
Well depends on the definition of 'army'.

Uniforms were first introduced during Louis XIV's reign in France. Mass conscription introduced out of bitter necessity during the French revolution when the whole of Europe declared war against France (and vice versa). I don't know when armies started relying solely on the government to provide for ordinance, pay and food (probably end 18th century).

First armies I guess would be located in early city-esque communities in Messopotamia and Egypt. Although I admit to knowing nothing about China, the Indus or Japan couple thousend years BC.
