Within 20 minutes two waves of RAF Chinooks, Royal Navy Sea Kings, Lynx and American Sea Stallions delivered 500 troops from 45 Commando Royal Marines and both British and Afghan special forces into three landing zones half-a-mile from enemy positions.

The Task Force Helmand commander, Brig Gordon Messenger called Operation Diesel a "clinical precision strike" that had "a powerful disruptive effect on known insurgent and narcotics networks in the area".

Four drugs factories were captured along with gallons of chemicals used to process opium into heroin.

Large numbers of machine guns were also recovered as well as a motor bike that had been primed as a suicide bomb.
