Why? BT would run a solid battle company, and you could get away with calling it a crusade. Just take every squad in a 5 man unit and spam razorbacks. 6 TAC squads, 2 assault squads, and 2 devastator squads. Keep everything cheap and just pay for the weapon mount upgrade on the razorback. That's 1000 pts right there. For your hq's take Grimaldus, because he has the zealot bubble, and a captain worth 100 pts. That's 1250 pts right there. Take the 3 land raider formation as your manditory second formation and you have what looks like a BT armored spearhead. Right? You have all the potency each squad needs with the weapon mount, you have 3 hard to kill land raiders, leading the charge, and everything has obsec. Templars are a hoard army and you have 50 Marines on the table and 13 metal boxes to move them around with. Templars can also make due if the razorback gets popped, because we have crusader. We can still run our asses off to each those objectives if we really need to get there.
