A new report from the RAND Corporation analyzed survey data from thousands of active-duty military members and found Marines are more likely to be heavy drinkers, use tobacco and engage in riskier sexual behavior than the sailors, soldiers and airmen of the other branches.

RAND found that incidents of binge drinking and hazardous drinking among Marines was almost double what it was in the Air Force.

The report defines binge drinking as having at least four or five drinks on one occasion. Hazardous drinking is defined as usage that suggests alcohol use disorder, commonly known as alcoholism.

Nearly half of the Marines surveyed reported drinking habits that met the criteria for hazardous.

The survey also revealed Marines were more likely to have had more than one sex partner of the course of one year and were less likely to use condoms with new partners.
