ARRC JOURNAL THE ARRC’S GROUND LIAISON ELEMENT ON EXERCISE TRIDENT JUNCTURE 2018 Colonel Richard Head, British Army “We are the best Ground Liaison Element in all the HRF(L)s in NATO...” we confidently announce to anyone who is briefed on the role of the Allied Rapid Reaction Corps’s (ARRC) Ground Liaison Element (GLE). This is always followed up, with a wry smile, “…because we are the only HRF(L) Ground Liaison Element in NATO!” However, things are changing and for the better. On the recent Exercise TRIDENT JUNCTURE 2018 (TRJE18) command post exercise (CPX), a newly trained team of five staff from the 1st German- Netherlands Corps (1GNC) teamed up with the two-person ARRC GLE team to provide the Land Component, played by 1GNC, with its own GLE inside the Air Component. The aim of this essay is to provide a brief overview of what the ARRC’s GLE does and look at the key themes that arose from this recent exercise as we worked alongside our comrades from 1GNC. GLE: A brief overview The GLE is comprised of land officers, embedded in the Air Component, who are placed in key roles within the various Air Component divisions to ensure that not only is the Land Component’s requirements met, but also, conversely, that any support that the Air Component requires is resourced by the Land Component. The GLE’s mission is to act as the Land Component Commander’s direct representative in the Air Component. They articulate his intent, priorities and provide advice across all functional areas both in the planning and execution phases of the Air Tasking Order, which is the mechanism through which the Air Component conducts its campaign. The numbers required to staff a GLE can vary, however at present it is 36 ALLIED RAPID REACTION CORPS Exercise Trident Juncture 2018 logo assessed that seven to 13 officers are required. Exercise TRITDENT JUNCTURE 2018 Following Exercise RAMSTEIN AMBITION 2018, an internal NATO Allied Air Command (AIRCOM) training event, which the ARRC GLE support on an annual basis by representing the Land Component, an invitation was extended by both AIRCOM and 1GNC who were due to play the role of the LCC on TRJE18 to be part of their own developing GLE capability. The offer was promptly accepted, particularly as it gave the opportunity to work as a GLE with a fully functioning 3-star Land Component. The element of TRJE18 that the ARRC’s GLE took part in was the CPX piece of NATO’s major 2018 exercise. Based on an Article 5 scenario in Norway, a joint campaign was conducted with AIRCOM; 1GNC; a maritime component headquarters based in Taranto, Italy with two members embedded as a Maritime Liaison Element (MLE) in the JFAC; a SOF component; and a significant Joint Logistic Support Group all working for JFC Naples. The exercise scenario was complex, multi-faceted, had significant depth to it and was suitably long (12 days) to provide the joint commander with a number of decision points where the competing priorities of the components could not all be aligned, and so prioritization and tough decisions were required at the highest level. Themes As can be imagined there were many lessons identified on the exercise. These often focused on low-level processes and the functionality of individual posts, as well as where GLE staff could be better placed within the Air Component. More importantly, though, a number of themes either emerged during the exercise or reinforced lessons from previous exercises. The top five were particularly key to understanding the role of the GLE and the underlying importance of cross component integration:
