The det would not have nearly 100 engineers. Having trailed with the Typhoons many times with 4 -6 a aircraft we took on average 18 Typhoon engineers. The exercise was designed to test many areas including;
1(Fighter) Squadron, based at RAF Leuchars, have been flying Close Air Support (CAS) training missions in Malaysia, working in conjunction with RAF Regiment Joint Tactical Air Controllers (JTACs), to further develop Typhoon Multi-Role capability.
The JTACs – who provide a critical link between air assets and those units requiring air support on the ground – forward deployed to the Cameron Highland Mountains in the centre of the Malaysian peninsula. Having carried out a thorough reconnaissance of the area, the JTACs from RAF Honington’s Air Land Integration Cell and 16 Air Assault Brigade took up positions deep in the jungle, from where they could provide accurate control to the 1(F) Squadron pilots.
The tropical terrain provides the Typhoon pilots from 1(F) Squadron and their ground-based colleagues with a rare opportunity to practice their skills in a difficult and complex jungle environment.
1 (Fighter) Squadron
I'm guessing total det was roughly 100 personnel. Edited to link to direct quote for P.
