Mid 1943 German armaments production.
Tanks. 6.4% of total armaments production.
Motor Vehicles. 4.8% of total armaments production.
Towing Tractors. 1.8%
8% Weapons (I assume small arms and artillery for the army).
Consumable stuff like ammunition, uniforms, field rations, commo wire, field radios, batteries, sand bags, concertina wire, helmets, fuel, sleeping bags, tents, field telephones etc. accounts for the majority of total munitions cost when an army is in large scale combat. That would apply to WWII nations like China, Japan, Germany and the Soviet Union.
Most of the U.S. Army did not experience combat until after the Normandy invasion. Consequently the USA could concentrate on production of military hardware to a greater extent then most other nations. Which is why the U.S. Army was so well equipped and supplied compared to everyone else.
