A little background in Khan’s services.

Khizr went on to work at the Washington, D.C., office of the law firm of Hogan & Hartson, one of the largest lobbying firms in the United States, where he was employed as the firm’s manager of litigation technology from 2000 to 2007.[7]
Lets likewise not forget that more service members have been killed by muds going postal than there have been muds service “members” killed in action.
