Daily admission rates of wounded-in-action (WIA) for combat troops ranged from 1.61 to 5.54 per 1,000 strength. The killed-in-action rates of combat troops ranged from 0.2 to 1.35. Support troop WIA admission rates ranged from 0.05 to 0.43 per 1,000 strength per day. Among wounded combat troops, the mean number of sick days before return to duty were 4.3 and 5.1 days for two different operations.
