M25

Where you get an idea of how crowded England, and in particular the South East is. The worst parts of the M25 are around Heathrow, the M1 and the Dartford Tunnel, where it really is a car park. It once took me two hours to go ten miles from junction 5 (Sevenoaks) to junction 6 (Godstone...what a joke. Obviously the worst times for traffic are weekday mornings and Friday afternoons. Large chunks of the M25 are only six lanes, making traffic problems worse. Sort it out!

The M25 is one of Europe's busiest motorways, but mismanagement means it usually has only six lanes, when compared to Europe's best roads.

M249

The fine line between psychosis and genius is measured only by the quantity of bullets that you dispatch from this gun into your victim.

It's essentially a big-ass machine gun with all the trimmings.

M249

The M249 SAW is the primary killing weapon of U.S. Infantry squads. The SAW is an air-cooled, belt-fed or magazine fed, gas-operated automatic weapon that fires 5.56mm ammunition. It has a regulator for selecting either cyclic fire (725 rpm) or sustained fire (1000 rpm). Unloaded it weighs roughly 15.2 pounds. Loaded with a 200 linked rounds it weights approximately 22 pounds. While it fires smaller rounds than the main platoon automatic weapon, the M240B, it weighs less and is more efficient for squad based operations.

Mechanized Whitlow unloaded his M249 into those bastards and cut them to shreds.

The M25

The M25 is the UK's least favourite motorway (yes we have least and most favourite motorways for some reason) due to its lack of speed cameras, road debris, confusing signage, poor lighting and dangerous junctions. Trips can take so long that the M25 has become well known in the UK for being where half of UK citizens are conceived and during the winters its where we all migrate to go and get stabbed by the chavs. Long story short, basically a very long car park that everyone hates.

M270 MLRS

A mobile rocket launcher used by the US military to compliment howitzer artillery fire, the MLRS (Multiple Launching Rocket System) can fire 12 M270 missiles in under 60 seconds.

Suddenly the area was quiet, then the insurgents heard the scream of 12 M270 missiles coming towards them.
