This was reportedly the youngest US serviceman killed in Vietnam

While most teenagers in the 1960s were worried about who they were going to take to the high school dance, Pfc. Dan Bullock was serving in Marine Corps and fighting against the communist guerilla army in North Vietnam.

At the age of 12, Bullock's mother passed away forcing him and his sister to pack their North Carolina belongings and move up north to New York where they lived with their father and his new wife in Brooklyn.

But due to an unhappy home life, Bullock set his sights on joining the Marine Corps.

As other young men in those days decided to flee toward Canada to dodge the draft, Bullock decided to adjust the date on his birth certificate from Dec. 21, 1953 to Dec. 21, 1949, so he could enlist in the Marine Corps.

His newly revised birth certificate convinced Marine recruiters enough to let him join the Corps at the ripe age of 14.

In May of 1969, and within six months after graduating boot camp, Bullock arrived in Vietnam ready to fight with his platoon. He would be killed a month later.

On June 7, 1969, Bullock suffered significant wounds from an enemy satchel charge while serving in the Quang Nam Province and passed away shortly after, making Pfc. Bullock the youngest American to lose his life in the multi-year skirmish.

But it wasn't until reporters visited Bullock's family home when they discovered the tragic news of Bullock's exact age — he was only 15.
