From the Weekly Standard:
During the 30-day religious celebration of Ramadan, even non-Muslims are expected to obey local laws regarding eating, drinking, and using tobacco in public. Violators can be fined up to $685 or receive two months in jail. A spokesperson for United States Central Command [CENTCOM] said that “we are not aware of any specific instances of anyone being arrested” for such violations.
\For [sic] military personnel outside of U.S.-controlled areas, the only exceptions for the rules are for those “performing strenuous labor.” Such personnel are “authorized to drink and consume as much food as they need to maintain proper hydration and energy.” It is unclear what constitutes “strenuous labor” or whether additional exceptions might be made during a heatwave affecting some areas of the region that has taken hundreds of lives.
When asked if the restrictions were new or simply a continuation of past policy, a CENTCOM spokesperson replied:
There has been no change in policy… [W]hile the US does not have a Status of Forces Agreement (SOFA) with the UAE, it is common practice to ensure all Soldiers, Sailors, Airman, and Marines deployed to Muslim countries are culturally aware that during the month of Ramadan, practicing Muslims do not consume anything from sunrise to sunset as a pillar of their faith. Commanders throughout the AOR create policies to ensure their subordinates respect the laws and culture of our hosts at all times….
