your captain realy dosen't need the extra attack from two hammer,s speicaly since it master crafted, so i'd swap out one for a storm shiled, that 3+ invunerable save is a godsend.

why so many teleport homers, when you only have one teleporting unit? it's a waste, as is the melta-bombs. You have crak grenades and will do best taking down tanks at range anywho

better to be safe than sorry

not realy, as the redeemer would be a MUCH better way to transport those terminators than unreliable deep strike that leaves them strended for a turn in front of the enemies heavy weapons...

My plan was to have Vulkan and the terminators in the redeemer and deep strike the chapter master near them and he joins the squad.

I was also wondering if you can give an auxilliary grenade launcher to someone with terminator armour, if not then I will give the chapter master digi weapns instead.

plan: *Facepalm* so not only do you plan on making the ultimate basket (vulcan would work much better giving the tac squads a much needed boost. Much, much better) but you also plan on making a 200 point character an ammo draw. one thing s8+ get's through his save and that's 200 points gone, and it's even more likely due to lack of storm shields...

grendade launcher: yep, it's legal ^_^

I will be giving him a storm shield to give him the added chance of survival.
