Joseph Brennan enlisted in the Army after his cousin, Sgt. Joshua Brennan was killed in action when his squad was ambushed on Oct. 25th, 2007 in the Korengal Valley of Kunar Province, Afghanistan. For his actions that day, fighting off the ambush and recovering the wounded Brennan from the clutches of Taliban fighters, then Spc. Salvatore Giunta was awarded the Medal of Honor.

Ever since that tragic date, Joseph has followed in the footsteps of his cousin Joshua.
