This is how Royal Marines used Apaches as troop transports during a rescue mission
It happened after an attack on Jugroom Fort went sour quickly. The Brits assaulted in armored vehicles with artillery and Apache support, and the insurgents returned heavy fire . Poor communication during the raid led to a friendly fire incident and another miscommunication led to the Marines withdrawing without Lance Cpl. Mathew Ford.
After rallying back up, the Marines quickly realized Ford was missing, and one of the two Apaches on the battlefield used an infrared sensor to spot what appeared to be a human silhouette just inside the compound. The Royal Marines quickly devised a plan to strap two Marines each to two Apaches and have them land just outside the compound.
