Is this what vikingz actually looked like ?

bbc loves bbc

He does look nafri. Not saying all or most nafris look like that, but if I saw someone like this in the streets I would assume he's moroccan.

I just checked and it's unlikely that troops from africa actually wore the redcoat as field uniform since the official corps for them were formed after it was phased out, although maybe they would have worn them as a dres uniform.
On the other hand apparently the caribbean colonies did have blacks regiments wearing redcoats.
Still not very common tbf.

I'd assume dominican, the guy on the pic looks like he has a broad nose insead of the typical moroccan semitic nose

Nah he doesn't, especially not like a 9th century one before middle ages slave trade

Dominicans are darker. But my second option would be some latam mutt, yes.
Quite irrelevant if they existed in those places or not anyways, since we don't know where the bbc guy is supposed to be and if I had to bet I would say Waterloo or the american revolution, both incorrect.
