The Israeli Army (IDF) automatically classifies any recruit who admits to being a D&D player with a low security clearance because it believes they are detatched from reallity, have "weak personality elements" and are - to be blunt - credulous fools. Ynet reports:
Army frowns on Dungeons and Dragons
IDF says players are detached from reality and automatically given a low security clearance

Does the Israel Defense Forces believe incoming recruits and soldiers who play Dungeons and Dragons are unfit for elite units? Ynet has learned that 18-year-olds who tell recruiters they play the popular fantasy game are automatically given low security clearance.
“They're detached from reality and suscepitble to influence,” the army says.
Now I've met some pretty weird D&D players but I am also aware of some remarkably smart tacticians who play too. This seems like a rather sweeping generalization. But I guess it could be good to know if you want to have a low risk role in the IDF.
