Nelson's men are now headed to Osan to join forces with the first American Army brigade sent to slow the enemy's rapid advance. An American Aircraft Carrier has just arrived and launched the first strike against North Korean bases. The 24th Infantry Division is landing at the port city of Pusan. An Airborne Battalion is ready to jump. The might of America's war machine is coming to bear in this hard-fought, gritty battle that unfolds. Colonel Nelson's men are right at the forefront of this non-stop action story.
