5.56x45mm NATO
The 5.56x45mm NATO round is a micro-caliber rifle round based upon the .223 Remington loading. In the US military, it is known as the M855A1 in it's most recent incarnation. In the rest of the world the 5.56x45mm NATO is known as the SS109.
Originally, the 5.56x45mm was designed with two goals in mind: Incapacitation, and weight reduction. The round was designed to wound a soldier, rather than kill them outright like the 7.62x51mm NATO round that came before it, as it would take two more soldiers out of the fight to take care of them.
Not only this, but the 5.56x45mm NATO is shorter and lighter than the 7.62x51mm NATO round that was it's predecessor, allowing troops to carry more ammunition.

The 5.56x45mm NATO round, also called the SS109, is the most commonly used Military-issue rifle round in the western world. However, it's usefulness has deteriorated against an enemy that does not value their lives, nor the lives of their comrades.

grebo
West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.
