Not really a turret. but their vehicle has always had a sort of raised 'turtle-back', and you can see the shell design on it if you go to a zoomed in view. Also, that slash of red wouldn't be Donatello, he wears purple. what it seems to be on the zoomed in view is sort of a periscope.
and yes. that's the thunder-tank, took me a minuite to figure it out cause the artist made a bad color choice on Lion-0. I think he's got too much blue and not enough yellow. Unless Panthro's driving is giving him a really bad case of motion sickness!!!
Hear that thunder rolling till it seems to split the sky?
That's every ship in Grayson's Navy taking up the cry-
NO QUARTER!!!
