This is slang that originated with American soldiers during World War II. Many US troops were armed with their fully automatic equivalent of the STEN gun, the M3 submachine gun which, because of its resemblance to the mechanic’s tool was called the ‘grease gun’. With the slightly macabre humour prevalent amongst those who are in combat, enemy troops killed by this weapon were referred to as having been ‘greased’.
It quickly came to mean killed by multiple bullet wounds from any type of machine gun. It was during the Vietnam War, however, that its use expanded and increased quite dramatically until it became used to describe any death in action against the enemy.
There is now some evidence to suggest that the word greased is being used to describe any violent death, even where this is not in combat and when it may even be an accident.

To be greased means to be killed. Originally it meant to be killed by multiple bullet wounds from a weapon fired on full automatic but gradually its use extended, particularly during the Vietnam War, until it was used to describe any death caused by enemy action.

The expression originated from American troops of the Second World War who were armed with the M3 submachine gun. Since the M3's nickname was 'grease gun', supposedly from its resemblance to the mechanics tool, enemy troops killed by the M3 were soon referred to as having been greased.
