Logistics:

During large wars, it is significantly easier to produce and equip
armies with standard sized uniforms. This becomes a more economical
way to outfit thousands of soldiers quickly and efficiently during a
war.

Psychological Warfa

In the past, uniforms were also used as a sort of psychological
warfare. Form enhancing gear that make the soldiers appear larger and
more formidable often strike fear into the opposing sides. Large caps,
capes, specific colors all add to the psychological warfare of the
military uniforms.

Modern day military uniforms are much more simpler. The US Army
soldiers wear standard camouflage utilities for practically all
purposes unless there is a dress parade or formal occasion where they
will wear their full dress uniforms. Today, the tradition and reasons
for wearing military uniforms still remain. It is unlikely that this
tradition will change drastically in the future.
