i personally feel that like having good equipments, uniform is
very important as it’ll affect the morale of troops. Germany fought
well in the beginning of WW2 and their
uniforms were designed by Hugo Boss, especially the Waffen SS. They
were almost invincible until the war with the Soviets when they
actually lost it due to weather. The Allies will have no chance at
all if Germany have enough supplies and fuel. A smart set of
uniform is a morale booster.
