Use of DUKW's on D-Day

[kevinT]

I have been asked to ask a question on behalf of someone who isn't registered.
Anyway here goes.
Were DUKW's actually used on Nan Red Beach on D-Day?
If so by which units and what were the AoS numbers and are there any on-line photos around?
Thank you for any help you can give.

Cheers
Kevin
