In book 3 of The Night Fighters, the Marines of CAP Tango-9 have to clear themselves of the drug charges brought at the end of book 2. In addition to that, they still have to deal with the corrupt assistant district chief, and defend Hou Bun village from the rampaging Viet Cong who keep coming through. This is the most difficult trial the Marines and the South Vietnamese Popular Forces have had.
