The worst space marine battle cry, post here what you think the most awesome, badass, fear-inspiring or generally the best Astartes battle cry is. Also post why you think so, so people can tell you are wrong when they post the ACTUAL best space marine battle cry.
Personal suggestions
Black Templars- "No Remorse! No Pity! No Fear!"
They use chains on their weapons as Sigismund did, who learned it from Kharn, and really like melee. Pretty savage, like the loyalist version of the World Eaters in a way, making their cry the loyalist version of BFTBG. Also, black armour, red eyes and the announcement that they will kill everyone without pity, guilt or fear is pretty frightening.
Deathwatch- "Suffer not the alien to live!"
Reinforces the Deathwatch role and the Imperial view of Xenos as a whole. Xenos are a cancer on the Imperium and must be annihilated, one the Imperium should not have to the suffer from. Knowing that the enemy doesn't see you as an opposing force, but a disease, is just insulting to say the least.
Salamanders-
Captain; "Into the fires of battle!"
Answer; "Unto the anvil of war!"
These call/answer cries are awesome anyway, but this one is full of their own culture and blacksmithing history and imagery. Also invokes their imagery of being the anvil on which the nemy is broken, and the fire which incinerates the heretic, traitor, daemon and xeno. Plus the Sallies are a cool chapter, and the black and red faces/eyes is scary.
Honourable mention; World Eaters- "BLOOD FOR THE BLOOD GOD!"
Imaging a thousand screaming, raving mad superhuman warriors dual wielding chainsaws, wearing inpenetrable armour, literally frothing at the mouth, backed by the literally embodiment of war, rage, killing, blood, skulls, heavy metal and total feth you, stampeding towards you at 40 miles an hour, screaming BFTBG and SFTST. Meanwhile, you are armed with a laser pointer and a Kevlar vest. And c'mon, who hasn't heard at least one person scream this at the top of their lungs as their Bloodthirster tears PapaSmurf's head off?
