<P> For a class project of Nicky's, Danny mentioned that when he was three years old, he wanted to be a firefighter for Halloween, but his grandfather Henry swore that as long as he was alive, no Reagan would ever be a member of the FDNY, got him into a police uniform, and he "never took it off" until he made Detective . </P> <P> On the job for 15 years (as of season 1), Danny took a leave of absence from the New York City Police Department to serve two tours in the Iraq War as a Marine . Danny saw combat in Fallujah, and was the only member of his platoon to come home alive (resulting in some post-traumatic stress). During his time in the Marines, Danny was decorated for heroism . </P> <P> He is old - school; his hotheadedness and harsh methods of detective work sometimes get him in trouble, which his father worries about . When asked if his son "crosses the line" and violates procedure from time to time, Frank answered, "I think he walks on the line". Danny is hard on other policemen and detectives when he feels they are unprofessional or not doing their duty to its utmost . He is currently assigned to the Detective Squad of the 54th Precinct, and partnered with Detective Maria Baez . In "Most Wanted", it is mentioned that he leads the Manhattan South Detective Borough in both collars and complaints . In "Love Stories", he and Baez are awarded the NYPD Medal for Valor for their actions in "Partners". </P> <P> As a detective with the NYPD, Danny carries a Kahr K9 in 9 × 19mm as his duty weapon, and drives a Dodge Charger on duty, which replaced his previous Chevrolet Impala 9C1 . He also owns a Glock 19 in 9 × 19mm, and previously used a Smith & Wesson 5946 in 9 × 19mm . Danny drove a Jeep XJ Cherokee as his personal / family vehicle from Season 1 to Season 5, whilst Linda drove a rather troublesome 2001 Kia Sedona / Carnival; this vehicle was replaced when Henry lost his driver's license and gave Linda his car . In Season 6, Danny's Cherokee was replaced by a fourth - generation Ford Explorer . </P>
