You've met the majority of the troops now here comes Big Mac Daddy Marneus Calgar.
The 40K 2nd Ed model is further down the page but for sheer blinginess, you can't beat his Terminator variant with attendant Honour Guard. I'm actually tempted to get the new Forgeworld HH Suzerain set just for more of the eagle masks but that will ultimately be dependant on the release of those HH plastics that have appeared around the tinternet AND FW having free delivery to GW stores. I am not paying FW P&P charges!
Metal Vanguard and Sternguard awaiting their plastic reinforcements.
I've singled out the Terminators below as these are prepared in advance just in case standard SMs get a Terminator Command Squad. They use a mixture of standard Terminators along with Grey Knight, Forgeworld and Wolf Guard bits.
