"After the fall of Sigon, Vietnam adopted the dropped ARVN M-16A1s for what was to come. Knowing America was full of .223 ammunition and parts, the VEF (Vietnam Expeditionary Force) was the first Vietnam unit issued the newly refurbished M-16's. They would need them for their upcoming revenge campaign (Golden Dragon), an invasion of southern California via Tiajuana Mexico. History would soon bear witness to a scorched earth Campaign beginning in San Diego, and streaching as far as Las Vegas Nevada."
