I worked for A company 1/46 Infantry 198th Light Infantry Brigade. We worked in the mountains West of LZ Baldy. We used scout dogs every time we could get them.
In November 1968 we had a scout dog team walking point when they flushed 15 NVA and VC. The dog handler was carrying an XM177E1 and fired it at he NVA. It jammed after 3 rounds, it pulled the rim off the case.
The NVA ran into a mature field of sugar cane. We surrounded the cane field then set it on fire and waited for them to come out.
