A 73 mm rocket round exploding delivered a mortal wound to Lee, which also injured Lex.

From around five years old, Lee worked with rescue dogs by hiding in woods and allowing them to find him.

[citation needed] On March 21, 2007, Company A's forward operating base was attacked by insurgents with indirect fire.

[4] Lee's parents, aided by United States Representative Walter Jones (R-NC) and an online petition, successfully asked the Marine Corps to allow Lex to retire early, making him the first fully fit military working dog granted early retirement and adoption by the Department of Defense to his former handler's family.

[2][4] After Lee's death, the Mississippi State Senate and House of Representatives passed a concurrent resolution honoring him.
