Red Bull Express? Red bull Dan? M113?

Question

I need to know who Red Bull Dan is and what was the "Red Bull Express"?

Answer 1

The Red Bull Express was an all-black trucking outfit that transported supplies to the front lines of Patton's Army in Germany.

The U.S. M113 ACAV was in production for over 30 years, longer than any other armored vehicle, M113 and its many sub-types serve in the armies of more than 50 countries. As this is written, over 40,000 M113's or variants have been built and delivered by FMC or its licensees. Battle proven in Vietnam, the M113 enabled a ten-man squad of infantry to travel behind protective armor in an amphibious vehicle that carried sufficient weapons to be considered an offensive weapon system.
Its ability to ford streams or even cross lakes made it an extremely useful vehicle in the waterlogged jungles of Vietnam.
As experience was gained with the use of the M113 in combat, numerous modifications were made to the vehicle to increase both its firepower and crew protection features.

I have no idea who Red Bull Dan was........
