"2) Some wanted to run or not fight but that the love for their fellow soldier AND the fact that Delta was there made the Rangers more willing to do things they otherwise would have questioned. They were all scared and wanted out badly."

As I said.

No American troops ran away from battle.

And yes, some had the opportunity. Recall the the "cook convoy?" Those guys (cooks, clerks, etc.) could have easily avoided battle, but chose to go into the fight instead.
