When Andy Lang began thinking about joining the service, he couldn't decide among the Air Force, the Army or the Navy. Family lineage solved the problem for him.

After all, his grandfather Chuck Lang served in the Navy with a construction battalion in World War II, detonating coral on Tinian, a South Pacific island where airstrips were built. Airstrips from which planes flew bombing missions that dropped the atom bombs on Japan.

And his father, Chuck, stationed on a communications relay ship in the Tonkin Gulf, served as a machinist in the Navy during Vietnam.
