I thought the sniper part was particularly fantastic.
In the same way as, say, Alice in Wonderland, or Star Trek, or Lord of the Rings, any film where you have to suspend logic and normal parameters.
The SAS were made to look like chumps and crass amateurs at ever twist and turn.
Firstly, they're taken by complete surprise by the US vehicle.
Then one SAS trooper is shot dead from a ludicrous range (800m) by an insurgent poking his weapon's muzzle directly out of an open window, thus giving away his position, from the only building for miles around, an AK47 to boot; so what does the US soldier do? Move position? Apply some simple soldiering skills of camouflage and concealment, does he adopt a more suitable fire position? Nope, the US sniper adopts the very same fire position as the last, now dead man, & proceeds to make extraordinary shots, including a moving target. Utter rubbish. It was, as you say, fantastic & completely unbelievable.
It just got worse as the film went on.
The sniper nonsense was but the tip of the proverbial iceberg.
I simply couldn't wait for it to end.
Was this a straight-to-DVD film?
