Since the 1990s, the U.S. Army has
banned the use of alcohol in combat zones. One side effect is fewer alcohol
related disciplinary problems. That means there are fewer cases of U.S. troops
getting in trouble with local civilians. Far fewer brawls, murders and rapes.
For example, last year, the U.S. Army had 2.6 cases of sexual assault per
thousand troops. But in Iraq and Afghanistan, the rate was .86. There were even
sharper drops in the number of assaults and murders. The use of alcohol has not
been completely eliminated in the combat zone, but it has to be obtained (from
locals, or stills run by troops) and consumed clandestinely. That alone greatly
reduces the amount alcohol related misbehavior.
