I've just seen this, which I'm not sure is a client-side addon or even if it will allow us to select weapons for A3 missions or if it might only work when playing A2 mission in A3 with AllinArma but it certainly looks interesting and if it does give us the weapon selection back in the Map and Briefing screen, is something we should use/recommend.
I was going to try the A3C_NameTag mod before A3 decided it wasn't going to launch anymore (turned out to be a Steam problem! An update has just fixed it but I've opted out of the Steam beta now as I think it only affected that). I didn't see any names last night either.
