They are considered Regulars, so yes. (thanks for the correction dirubin)
Here are some comments from the designer on that question:
2. French Marine detachments - what's with the VP liability?
One (I hoped) subtle way that I tried to get at the fact that drilled French forces in the New World were a more limited and therefore precious asset than British counterparts. (Unlucky British players cursing their lack of WW reinforcement cards are free to differ, naturally.) British Light Infantry included healthy dolops of provincial folk, and Provincial Regiments are just colonials and a dime a dozen for the Crown anyway (or so was thought until 1775 or so).
In terms of gameplay, I wanted to French player to agonize about whether to stand fast with these little Marine detachments or to scamper. In any event, with tourney pros ruling the French as favored, just as well that the French have this liability.
