Figures released by the Ministry of Defence show how bombing missions by pilotless aircrafts were effective. The flight logs reveal how RAF MQ-9 Reaper drones, which are controlled by military crews in bunkers located in the UK, have been deployed on 4,107 missions in Syria and Iraq since 2014.
Some of the drone and missile strikes were supported by US forces.
The drones used by the British forces can travel at 287mph and fly at over 30,000ft.
They can also carry 500lb bombs or Hellfire missiles used to strike a target.
Royal Air Force figures have shown that 972 terrorists have been killed or injured in Iraq since 2014.
Thirteen of those targets were struck this year.
In Syria, 437 targets were hit in the past six years.
However, the total figures are an estimate based on photographic evidence and debris left at the scene.
Military operators watch drone and missile strikes through live feeds to track the hit and impact.

The RAF Typhoons hastened towards the Russian aircrafts after they “entered the UK’s controlled zone of international airspace”.
A MoD spokesman said monitoring of the zone is done to ensure the safe passage of other aircrafts.
The US also launched an extensive drone bombing campaign against ISIS, killing large numbers of its fighters including Britons.
Mohammed Emwazi, also known as ‘Jihadi John’, and the ‘White Widow’ Sally Jones were both killed in the strikes.
Mr Emwazi was targeted for beheading hostages and he was killed in Syria in November 2015.
Jihadi John was responsible for taking part in the executions of seven western hostages and at least 22 Syrians for ISIS propaganda videos.
During the videos he always appeared in a mask and he beheaded western hostages including two Britons, David Haines and Alan Henning.
Ms Jones, who was a British born extremist, fled Kent in order to recruit for ISIS in Syria.
She reportedly died in a strike in June 2017 and her 12-year-old son JoJo is also believed to have been killed.
