For over 100 years, the United Kingdom and the United States have fought alongside one another as we, together with our allies, have sought to protect our way of life and help shape a bright and prosperous future for our children and grandchildren. As brothers in arms, we have fought two world wars, brought about the end of the Cold War, and operated side by side in Korea, the Balkans, Iraq and Afghanistan. Like all close friends, there have been disagreements—think Suez and Vietnam—but the relationship between the U.K. and U.S. militaries is, today, closer than that of any other two nations.

And the relationship at the army level is deeper still, marked by defining personal partnerships and shared sacrifices on the battlefield, probably especially so for the current generation of mid- to senior-level leaders who have common experiences in Afghanistan and Iraq.

But what of tomorrow’s leaders? What of the relationships between those young men and women in our respective armies who may be called upon to lead in combat should great-power competition stray into armed conflict? It is questions such as these that drive the British and U.S. Army’s current interoperability work to ensure, bilaterally and as part of an alliance, we are ready to deploy, fight and win together on the future battlefield.

This interoperability work is framed within the British Army and the U.S. Army’s 2013 “Strategic Vision for Future Bilateral Cooperation,” signed by our respective army chiefs, the crux of which is: “to enable a UK division to operate effectively within a US corps and a UK brigade to operate effectively within a US division, and to enable a US Brigade Combat Team to operate effectively within a UK division and a US division to work effectively within the UK-framework NATO Allied Rapid Reaction Corps.”

This statement reflects the deep trust and faith the countries have in each other, and the progress in the ability to work together has been significant. This is hardly surprising because, just like the U.S. Army, the British Army is a committed, capable and like-minded partner.

Committed Worldwide

The British Army is committed to operations around the world alongside U.S. forces. The U.K. has troops deployed in Afghanistan, Iraq, Ukraine and the Balkans. We have numerous training teams in Africa; Nigeria is a key focus area, but we also conduct capacity-building in other African countries, including Somalia, Sierra Leone, Algeria, Kenya and Ethiopia, where activity is synchronized with the U.S. Army to ensure both countries’ resources are employed in the most effective manner.

The U.K. and U.S. also are leading nations in NATO’s Enhanced Forward Presence mission in Eastern Europe, with battlegroups committed to Estonia and Poland, respectively. The U.K. has about 1,000 troops deployed across Eastern Europe, including a British Army reconnaissance company under U.S. command in Poland.

Additionally, the British Army is training for operations around the world alongside U.S. forces. We do this at multiple levels:

  • Corps: NATO’s U.K.-led Allied Rapid Reaction Corps is ready to deploy as a corps, land component or high readiness force (land) headquarters. It is a highly trained and respected headquarters that exercises routinely with multinational forces. For example, in 2020, the Allied Rapid Reaction Corps will provide the high command to a U.S. division in the Defender exercise, when a U.S. division will deploy from America to Europe to execute deterrence options. The British Army’s contribution to this U.S. Army Europe-led exercise is considerable; as well as Headquarters Allied Rapid Reaction Corps providing high command for a U.S. division, we will also provide headquarters elements from an armored infantry brigade, an artillery brigade, a logistics brigade and a helicopter force, as well as some amphibious bridging assets.
  • Division: The British 3rd Division has taken part in the U.S. Army’s Warfighter series of exercises over the past few years and will continue to do so. In 2018, the British 3rd Division operated alongside the American 4th Infantry Division with the XVIII Airborne Corps at Fort Bragg, North Carolina, and this April, the British 3rd Division operated alongside the U.S. 1st Armored Division under III Corps at Fort Hood, Texas. These are fast-paced, high-end combined-arms maneuver exercises against near-peer adversaries that test human, procedural and technical interoperability. The British Army is the only foreign army to exercise with the U.S. Army at this level.
  • Brigade: Every year, one of the British Army’s brigades takes part in the U.S. Army’s Joint Warfighting Assessments, in which brigades from several nations operate as part of a U.S.-led division to further develop cutting-edge concepts and capabilities. In May, the headquarters of the British 1st Armoured Infantry Brigade deployed to Joint Base Lewis-McChord, Washington, under the 7th Infantry Division. And in 2020, the headquarters of the 20th Armoured Infantry Brigade will deploy to Europe under a U.S. division. Additionally, the British Army’s 16th Air Assault Brigade has a close relationship with the 82nd Airborne Division; indeed, it deployed under the command of the 82nd during Exercise Swift Response in June of last year.
  • Battalion: The British Army’s battle groups train for combined-arms maneuver at training areas around the world. Our primary field training areas are in Canada for armored training and Kenya for light forces training, but we also send six companies each year to the U.S.: two reconnaissance companies to the National Training Center at Fort Irwin, California, and four light infantry companies to the Joint Readiness Training Center at Fort Polk, Louisiana. Additionally, a platoon from the 82nd Airborne Division deployed to Kenya last year under the command of one of the British Army’s parachute regiment battalions.

Capable of Command

The British Army invests heavily at all echelons of warfighting, from company to corps. In addition to the series of U.K./U.S. exercises previously described, every level of command trains routinely for high-end combined-arms maneuver. We are particularly proud of our level of investment at the division and corps levels.

For example, at the corps level, Headquarters Allied Rapid Reaction Corps’ Joint Fires and Influence Branch participates, about every other year, in Exercise Dynamic Front, U.S. Army Europe’s primary annual fires integration event. At the divisional level, our artillery brigade is also a key component of Dynamic Front, but likewise participates in the Warfighter series of exercises. By so doing, we have successfully plugged into the U.S. Army fires architecture at multiple levels, and exercised command of U.S. artillery battalions.

We also work side by side with the U.S. Army in the train-advise-assist-accompany space. As the U.S. Army continues to develop its security force assistance brigade work, so too is the British Army developing similar “specialised infantry group” work. The U.S. Army has an SFAB deployed in Afghanistan, and we have specialized group teams deployed in Afghanistan and Nigeria. The countries share insights and lessons and learn from each other.

The British Army is also focused on modernization and experimentation to ensure we remain capable and compatible with allies and partners, but particularly with the U.S. Army. Much like the U.S. Army’s modernization agenda, we too are focused on identifying and procuring the capabilities required to prevail in future conflict.

And to help shape investment decisions, we have embarked on an ambitious experimentation agenda. We conducted the U.K.’s largest military robotics exercise in late 2018, with support from a squad of U.S. infantry. Early findings have encouraged our secretary of state for defense to commit nearly $100 million to fast-track a number of projects this year. Several of these will be deployed to operational theaters by the end of this year to enable experimentation on operations as well as in training.

We have also made our experimentation work mainstream business. We have tasked one of our brigades to focus exclusively on fielding modernized strike capability and develop the tactics, techniques and procedures required for future speed of assembly and delivery of rapid and strategic projection and effect.

Like-Minded Through Schooling

If the U.K. and the U.S. are to fight and operate side by side, then both countries need men and women in our armies who understand each other’s concepts, doctrine and planning processes. One way to do this is through shared professional military education. The respective investment in this area is unparalleled.

For example, every major in the British Army spends two weeks at the U.S. Army Command and General Staff College at Fort Leavenworth, Kansas, as part of their six-month staff training course, during which British and U.S. Army majors focus on planning and running divisional-level operations using planning processes from both countries. Aside from the doctrinal and broader educational value, the opportunity for tomorrow’s leaders to get to know one another in a relaxed, convivial environment is invaluable.

But this is only one of numerous examples where British Army personnel from sergeant major to three-star general attend U.S. Army (and joint) courses, and vice versa, ranging in length from two weeks to a year. Other examples include British soldiers attending U.S. courses such as Pinnacle, Capstone, the U.S. Army War College and the U.S. Army Sergeants Major Academy, and U.S. soldiers attending British courses such as the Royal College of Defence Studies, Higher Command and Staff Course, and Advanced Command and Staff Course.

Both the British and U.S. armies provide strong and like-minded leadership in key British, U.S. and NATO positions. Within the U.S. Army, the British provide a two-star deputy commanding general at III Corps and one-star deputy commanding generals at the 1st Armored Division and the 82nd Airborne Division. And within the British Army, the U.S. provides a one-star deputy commanding general at the British 3rd Division and a one-star deputy commander of operations at Headquarters Allied Rapid Reaction Corps.

More broadly, the British Army fills numerous senior leadership positions during operations, e.g., the three-star deputy commander in Afghanistan and the two-star deputy commander in Iraq. And at lower levels, although no less important, there are a multitude of NCO to colonel exchange positions on both sides of the Atlantic.

In an era of persistent and intense competition, when adversaries and competitors are becoming more adept at exploiting the seams between peace and war, the trans-Atlantic defense relationship becomes ever more important. This partnership is unparalleled at multiple levels: from nuclear and intelligence cooperation, to decades of combined operations and training overseas, which has ingrained interoperability across the maritime, land and air domains, and with Special Forces. At every level, this strong connection between the U.S. and U.K. militaries means a great deal to us. It has depth and an emotion to it that is profound.

The U.K. and the U.S. have fought side by side for more than 100 years. We are proud of this shared history, and equally proud of the current level of investment in ensuring the British Army remains a credible warfighting partner today and, importantly, tomorrow.
