Well, I think Fougasse has pegged pics 1,2 and 5, although I thought the scarlet band around the hat (picture 5) was an MP thing. Maybe that's just in Canada.

But as far as pics 3 and 4 go, it doesn't look like they're JDF. I've just surfed through the JDF's website, and the weapons are all different. When doing stuff at Buck Palace, the Canadian's carried their own weapons rather than "borrow" the British ones. I can't see the Jamaican's doing anything different.

Rats! Discussing weapons is a big no-no on this site! I beg the moderators indulgence, as this was an aspect of deducing who was in the photos, and not a discussion of the weapons per se. Regardless, I will not discuss them further, and I just mentioned it as a clue to who is in the photo.

If this is judged to be a transgression of the rules, I offer my apologies in advance, as well as my apologies to anyone who may be offended.
