I went to the medical treatment of chemical and biological casualties at Aberdeen and Ft. Detrick years ago and learned this from a renowned Army colonel.
The Russians developed an anti-facility agent that affected the different U.S. services in different ways. It destroyed the Army's tents and associated equipment making the U.S Army ineffective as a fighting force. Since the Marine Corps gets all the Army's hand-me-downs then, see above. The Navy would be assaulted with an anti-metal agent that caused immediate rust on the ships making them ineffective. The agent planned for the Air Force was a chemical that burned golf course grass which on it's face, should not cause a degrade in military readiness. According to the Russians, the Air Force would be so distraught at the loss of their golf courses that their budget of weapons and planes would be drained due to the rebuilding process.
