I finished up the last of the Cold War British I have (for the moment!) over the weekend. Here's what IU've got so far:

Regular infantry platoon. At some point I'd like to mechanize these lads with some FV-432s or Saxons... (and maybe a few more Carl G Teams)

Some support for the infantry: Milan, Mortar, Sniper and Forward observer team.

I also seem to have a few spare troops armed with SMGs - perhaps they can be dismounted drivers...?

Finally some special forces types - SAS or Royal Marine Arctic and Mountain Warfare Cadre...
Now to finish up some adversaries and get these guys into action!!
