Capt. Donna L. Cottrell, the commanding officer of the Coast Guard Helicopter Interdiction Tactical Squadron, addresses guests Friday, April 18, 2014, during a change of command ceremony in Jacksonville, Fla. The change of command ceremony is a time-honored tradition that represents the transfer of one commanding officer to another as well as the transfer of absolute authority and responsibility for a military unit.
