I meant either slow but steady march up field with termies in land raiders. Lysander as HQ option. Either that or vanguard and sternguard troops up either T1 or T2 to alpha strike key enemy positions. Use land raiders and heavy armour as fire suppression until in range to assault. Prefereably assaulting in T2.
Have seen a deathwing force, which seems to be the best combination in this method, but don't like DA personally in 6th. My usual choice is FA troops flying down the board, cover to cover, until reach target, paired with drop pod sternguard squad, but am considering 'mixing things up'
