So, I'm looking at a couple BT lists with a similar core, and trying to decide how I want to round the army out. The decision basically comes down to whether I want to walk my terminators behind rhinos and use them as a counter-assault/second wave assault unit, or if I want to put them in a LRC and use them as the spearhead the rest of my army follows behind. I'm really worried about my 300-point land raider soaking a meltagun or something and being destroyed before I get to move it, but if I don't take it I'm concerned about volleys of small arms fire (basically from venoms) whittling down the assault terminators if some guy has an arm raised too high between rhinos or something. The other major change I'm debating is swapping the vindicators for more troops - essentially addressing the same problem, where one good shot means my 160 point tank is driving around and ignoring shaken results on its storm bolter the rest of the game.

Current List (with LRC/vindi's):
140 - Emporer's Champion - Accept Any Challenge
213 - Crusader Squad - 6 initiates, 3 neophytes, melta, power weapon, frag grenades
.. -> Rhino, Extra Armor, Smoke Launchers
193 - Marshal - LC, SS, Artificer armor, Terminator honors, Adamantine Mantle, frag/krak grenades
218 - Crusader Squad - 6 initiates, 3 neophytes, melta, power fist, frag grenades
.. -> Rhino, Extra Armor, Smoke Launchers
599 - Sword Bretheren Terminator Assault Squad - 3 LC/LC, 4 TH/SS, furious charge
.. -> Land Raider Crusader - Blessed Hull, Dozer Blade, Smoke
101 - Crusader Squad - 5 initiates, plasmagun, lascannon, 3x boltguns
70 - Land Speeder - Typhoon missile launcher, heavy bolter
158 - Vindicator - Smoke, PotMS
158 - Vindicator - Smoke, PotMS
