English to latin translations

Can anybody help me translate these mottoes into Latin?

Blood and Steel

Guns in the Sky

Death in the Night

Bringer of Death

Thank you.

Some words--steel and guns--did not exist back in 100 B.C.
So I put in the closest equivalent.

Also I am not sure how to construct the noun "bringer" out of the verb.
But "Casso" which means "to bring to naught, destroy, annul or make void" really really fits the bill.

Blood and Steel
Ferum cruento

Guns in the Sky
Armae ex caelum

Death in the Night
Letum in nox nocte

Bringer of Death
Casso leto
