Yankee. You neglected to mention the Korean War era rations you were likely indigesting.
However, deterioration of munitions is a real world logistical concern. Most nations attempt to maintain a 30 day combat supply, but the former Sovs and clients have stockpiled literally generations worth.
Fuel is actually the most perishable of stock, lasting only 1 year on average.
That is all lovely trivia, however, it begs the question "of all the realistic changes W3C could make to its current war engine, why do why begin with this one that involves destroying massive amounts of player assets without compensation?"
What next? Armored vehicles disappear from stocks due to tread wear?
Interceptors dissappear due to stress fractures on landing gear perhaps?
But back to the war engine. Has anyone determined that quality ever had any effect on simcombat?
