..the USMC lost on 2 July 1967.....the NVA set a huge ''ambush''..they decimated a whole company/etc......the USMC lost that fight......now, when they brought in reinforcements, the next day/etc, then the NVA took more casualties .....The American Forces never lost a straight fight with the NVA/VC. Needed to add more Special Forces for fighting the VC. The VC use proper guerilla warfare on the American Forces which inflicted heavy casualties on US forces. The VC use the jungles to its benefit and had a better organize guerilla force. The VC tactic was well planned out and help cause confusion. The heavy use of underground bunker help NVA/VC in this conflict. The American search and destroy had some success but could have been improve if used the right way with more special unit design for the jungle environment. Overall the mistake the US made in Vietnam has caused the US to change it tactic and Afghanistan is prime example of this new tactic which is working look at the casualtes.
..also at the Ia Drang LZ Albany the NVA kicked some a$$.......
..remember, the US had HUGE advantages: airpower and choppers/naval/ etc---the NVA did well against the US
..the USMC considered the NVA worthy adversaries
..MACV SOG lost a lot of Spec Forces....
