Abstract:
Daily rates of disease and nonbattle injury (DNBI) incidence were analyzed and compared for four ground operations: Okinawa, Korea, Vietnam, and the Falklands. Average daily DNBI admission rates among operations ranged from 0.99 per 1,000 strength to 4.03 for combat troops. Average daily admission rates for support troops ranged from 0.71 to 1.15. Among combat troops, between 26 and 38% of DNBI presentations were of a nature that precluded returns to their unit due to a medical transfer; among support troops, less than 17% were not returned to their units due to transfers.
