Disposible Heroes and For Whom the Bell Tolls. Two of the best War Heavy Metal Songs ever. Well can’t forget any of the Maiden War Sons. Where Eagles Dare, Tail Gunner. Bruce Dickison was a lyrical genius with the War War two knowledge..
Metallica - One
slayer - mandatory suicide, ghosts of war, angel of death
megadeth - holy wars
I am more of an American Thrash Metal guy ala the Big 4, but maiden is incredible.
Live After Death is probably the best live metal album of all time.
