Did the US Order of Battle on D-day include Negro infantry regiments?

There were only two all-black Infantry Divisions in WW2: 91st and 92nd Division. There were some independent infantry regiments and other support troops, including a tank battalion. The 320th Anti-aircraft Artillery Balloon Barrage Battalion was an all-black unit that landed on D-Day.

This is the most famous black unit in France. The 3275th Quartermaster Service Company landed on Omaha Beach but I'm not sure if it was the first day, as supply units may not have arrived that soon. In conclusion, I would say there were NO all-black infantry regiments that landed on D-Day on 6 June.
