Not quite. CO19 have both - AFOs crew the ARVs and provide static protection at key locations, SFOs are used in tactical teams (although they'll also be used for other roles). There's also the Diplomatic Protection Group, as well as various other teams and units which the MPS prefers to keep out of the public spotlight.
In any case, just because some different equipment is being used doesn't mean it's special forces or anything like that.
Well wiki'd, but not quite. If you read the various articles, CO19 are the SFOs like I said (the clue is in the full name of Central Operations Specialist Firearms Command). They provide training to other AFOs. CO19 are the only ones that receive advanced training that make them SFOs. The DPG are AFOs.
Like any other section not CO19. Yes CO19 are used in tactical teams, but they're not AFOs. They simply assist them a lot.
Anyway, I've been doing a bit of googlefu (since it was look up that stuff or waste time on Reddit). I was wrong earlier when I said the guy was wearing a utility vest. It's a plate carrier but without the cummerbund. That's why I mistook it for a vest. And yet, it's still unique to any other picture I've seen of SO/CO19 body armour.
Here's another picture from today, similar vest without the cummerbund. Small, like the first one I commented on. Not like any picture so far I've seen of SO/CO19 which are larger ballistic vests, or even the vests the RUC/PSNI use. Pictures from when they were hunting Raoul Moat had guys in civvies, but using SO/CO19 vests. Some said it was the SAS, but then the SAS don't have powers of arrest and it wasn't a terrorist incident, so who knows. But they weren't wearing balaclavas (nor was any single one of them using a chest holster) so I'm assuming they were police. And as I mentioned Task Force Black earlier, British special forces seem to like
picking and choosing what kit they want for the task at hand. And plate carriers appear to be uniquely military from what I've seen so far.
But there was someone in SO/CO19 gear wearing a
three hole! YAY! Who seems to be directing the action. While the chap beside him isn't wearing a balaclava at all. Nor does it appear that the guy further inside is either.
