by Hank AckerFollow the USMC Recon Marines as they airdrop into North Korea during the Korean war. Their objective is to destroy tunnels and caves and prevent their use by the enemy. Storing war material and munitions out of sight was a priority for the North Koreans and the Chinese Army. The Recon Marines job is dangerous, difficult and highly secret. The involvement of many other service personnel makes the story both interesting and compelling.
