In August, the U.S. Air Force airdropped more than 100,000 prepackaged meals and 30,000 gallons of drinking water to refugees in and around Mount Sinjar in Iraq. The food items came from a specialized menu that follows Islamic guidelines.

Of course, the majority of the individuals near Sinjar were members of the Yezidi faith, not Muslims. But the Pentagon didn’t take any chances. The military no doubt wanted to make sure nobody trapped on the mountain top went hungry.

Shariʻah law has very detailed rules about preparing meats and bans Muslims from eating pork altogether. Strict adherents of these restrictions must eat food that is halal—permitted by the Quran—unless there are absolutely no alternatives.

With these requirements in mind, the Defense Department’s Combat Feeding Directorate developed meals for both observant religious personnel and humanitarian aid. The resulting “Meal, Religious, Halal” consists of an entree and an accessory pack.

Halal-certified main courses include lamb and chicken dishes, as well as vegetarian options like cheese tortellini and pasta with vegetables, according to a U.S. Army fact sheet.
