Footage that allegedly shows a group of men practising military-style techniques in a New Forest terror training camp has been seen by a jury.
A British Army officer told Woolwich Crown Court that the drills were similar to those of al-Qaeda insurgents in Iraq and Afghanistan.
He said the mobile phone footage, shot in Hampshire, was also reminiscent of basic Army training.
Five men all deny charges of being involved in setting up training camps.
Among them is Mohammed Hamid, 50, who prosecutors say set up camps attended by the 21 July bomb plotters.
The other men are Mousa Brown, Kibley da Costa, Mohammed Al-Figari and Kader Ahmed.
The trial heard that Mr da Costa, Mr Hamid and Mr Ahmed all took part in the New Forest camp, but the other two defendants did not.
The jurors heard that several short clips from the New Forest trip were recovered from a computer owned by Mr da Costa.
They were told that the three men travelled to the New Forest on 28 April 2006 for a four-day camp.
The British officer, referred to as Soldier A, said the activities shown were similar in some ways to basic Army training.
Mohammed Hamid is charged under the Terrorism Act 2006 with providing weapons and terrorist training. He faces additional charges of soliciting murder, and one charge of possessing terrorist documents
Mousa Brown is accused of providing and receiving weapons training
Kibley da Costa is charged under the Terrorism Act 2006 with providing terrorist training and with attending terrorist training camps
Mohammed Al-Figari is charged under the Terrorism Act 2006 with attending terrorist training camps
Kader Ahmed is charged under the Terrorism Act 2006 with attending terrorist training camps
He drew attention to one particular clip which showed a man identified as Mr da Costa bouncing on his knees between two positions while holding a large stick in front of him.
"I have seen that used as a method of carrying a weapon system," Soldier A said.
"It is not something that is taught by the British army. I have seen it used by insurgents while in Iraq and the Taliban in Afghanistan.
"It is a favoured position of insurgents and Taliban."
Prosecutor David Farrell QC then asked him: "With what type of weapon?"
He replied: "An AK-47."
In another clip, two men are seen performing a series of forward rolls, again holding a large stick in front of them.
Off camera, someone is heard to shout "Don't waste time."
Soldier A served as an infantry platoon commander on three active tours and now works as a British Army instructor.
He told the court that so-called "leopard crawling" shown in the footage might be used to approach an enemy, while wrestling and other drills seen could improve agility.
The trip was one of a series of trips taken by the five men including paintballing, camping in the Lake District and visits to an Islamic centre in East Sussex.
The court also heard evidence from an undercover police officer who infiltrated the group claiming he wanted to convert to Islam.
Kibley da Costa was identified in the footage shown to the court
He attended a number of meetings at Mr Hamid's home in Clapton, east London, and eventually a number of the alleged training camps.
He told the court about a conversation he had with Mr Hamid's co-defendant, Mr da Costa, during a car journey before the New Forest camp.
"He said the group were extreme but it was the right way to be," the officer said.
Police hid a bugging device in Mr Hamid's home in September 2005.
In one recorded conversation played to the court, he is heard telling a group of men: "Remember this, Allah has turned around and said every Muslim should be fully trained.
"He should be able to take on two kuffar [non-believers], right, he should be ready for jihad."
The trial continues.
