I'm curious about the 'we hooked in there for hours' part. It mentions 6th btn and Nui Dat. Does this mean that this part of the song is about Long Tan, were D company was up against an entire regiment of NVA?

I believe that the hooked in there for hours part is about D Company, 6th Battalion at Long Tan. Means a bit as D Coy 6 Bn was the sponser of my training platoon at Kapooka when I enlisted in the Australian Army and I had the honour of meeting veterans from this battle.
