While the U.S. has ordered its soldiers to remain sober in every major deployment since the 1990s, not all militaries have jumped on the temperance convoy.

Here are five militaries with service members still allowed to drink in a war zone, as long as the mission and security situation permits it.

Germany is famous for its beer, so it's not surprising that it allows its soldiers to imbibe a little while deployed. The soldiers are limited two beers a day while at larger bases. The sheer size of the alcohol shipments caused a debate in Germany early in Operation Enduring Freedom, but the booze kept flowing.

2. Canada

Before Canada pulled out of Afghanistan, they offered their troops two beers and a half bottle of wine while at well-secured locations.

3. Italy

Italians receive small quantities of alcohol in their ration packs and also deployed so much other wine that it flooded the black market near some bases in Afghanistan.

4. France

French soldiers on well-defended bases were sometimes allowed to drink during "Happy Hours" and other command-approved events.

5. Romania

Like their French counterparts, Romanian soldiers could drink during specified periods provided they weren't on duty and didn't get themselves in trouble.
