COMMENTARY / Jairo Císcar Ruiz

At the end of last summer, two news pieces appeared in the forums and specialized magazines of the military field in the Anglo-Saxon world. The first of them was the forecast of the continuity (and worsening due to the current pandemic) of the spending cuts suffered in the UK Defense budget since 2010. The second, linked to the first, was the growing rumors of a possible withdrawal of the Challenger 2 tanks, which were already reduced to a quarter of their original strength. At a time of great economic instability, it seemed that the UK's strategic vision had decided to focus on its main assets to maintain its deterrent power and its projection of force: the very expensive nuclear arsenal and the maintenance and expansion of new naval groups in order to host the F-35B.

However, both pieces of news have been quickly overtaken by the announcement of the Boris Johnson executive to inject about 22 billion dollars over 4 years to take British power back to the levels of 30 years ago. Also, the decommissioning of battle tanks was dismissed by ministerial sources, who argued that it was simply a possibility raised in the "Integrated Review" that is being carried out by the British Ministry of Defense.

Although the waters have calmed down, the debate that has arisen as a result of these controversies seems extremely interesting, as well as the role that armored units will have on the battlefield of the future. This article aims to make a brief reflection, identifying possible scenarios and their implications.

The first of them It is a reality: the United Kingdom must improve its armored forces, which run the risk of becoming obsolete, not only in the face of threats (Russia has had since 2015 the T-14 Armata, a 5th generation tank; and recently the modernized version of the mythical T-90, Proryv-3), but also in front of their allies, such as France or Germany, which are already starting the project to replace their respective armor with the future European Main Battle Tank. It is not only a matter of improving their operational capabilities, but also of evolving their survival on the battlefield.

At a time when military technology is advancing by leaps and bounds (hypersonic projectiles; battlefield dominated by technology; extensive use of drones ...), it is necessary to rethink the traditional way of waging war. In the last Nagorno-Karabakh crisis, images and evidence of the effectiveness of the use of Israeli “suicide” drones could be seen against groups of infantry, but also against armored vehicles and tanks. Despite Foreign Policy accusing poor training and the complex terrain as the main factors for these casualties, the question is still up in the air: does the "classic" tank as we know it still have a place on the battlefield?

Experience tells us yes[1].  The tank is vital in large military operations, although, as noted above, new threats must be countered with new defenses. To this day, the tank remains the best vehicle to provide direct fire quickly and efficiently, against other armor, infantry, and reinforced enemy positions. By itself it is an exceptional striking force, although it must always act in accordance with the rest of the deployed troops, especially with Intelligence, Logistics units and the Infantry. It should not be forgotten that in a battlefield characterized by hybrid warfare, it is necessary to consider the increasingly changing environment of threats.

Sensors and detection systems on the battlefield are persistently more innovative and revolutionary, capable of detecting armored vehicles, even if they are camouflaged; when integrated with lethal precision firing systems, they make concealing and wearing heavy armor a challenge. There are technical responses to these threats, from countering electronic direction finding through spoofing and interference, to mounting active protection systems on vehicle hulls.

Despite the above, obviously, the battle tank continues to be a great investment in terms of money that must be made, questionable in front of the taxpayer in an environment of economic crisis, although at the strategic level it may not be.

There are also those who broke a spear in favor of withdrawing the tanks from their inventories, and it seems that today they regret having made this decision. The United Kingdom has the example of the army of the Netherlands, which in 2011 withdrew and sold to Finland 100 of its 120 Leopard 2A6s as a means of saving money and changing military doctrine. However, with Russia's entry into Ukraine and its increasing threats to NATO's eastern flank, they soon began to miss the armored forces' unique capabilities: penetrating power, high mobility that enables turning movements to engulf the enemy, maneuverability, speed, protection, and firepower. In the end, in 2015, they handed over their last 20 tanks (crews and mechanics included) to the German army, which since then has a contingent of a hundred Dutch, forming the Panzerbataillon 414. Knowing how important the concept of “lessons learned” is in military planning, perhaps the UK should pay attention to this case and consider its needs and the capabilities required to meet them.

A roadmap to the middle position would be to move towards an “army of specialization”, abandoning its armored units and specializing in other areas such as cyber or aviation; but this would only be possible within the framework of a defense organization more integrated than NATO. Although it is only a distant possibility, the hypothetical and much mentioned European Army -of which the United Kingdom would most likely be excluded after the Brexit- could lead to the creation of national armed forces that would be specialized in a specific weapon, relying on other countries to fulfill other tasks. However, this possibility belongs right now to the pure terrain of reverie and futurology, since it would require greater integration at all levels in Europe to be able to consider this possibility.

In the end we find the main problem when organizing and maintaining an army, which is none other than money. On many occasions this aspect, which is undoubtedly vital, completely overshadows any other consideration. And in the case of a nation’s armed forces, this is very dangerous. It would be counterproductive to ignore the tactical and strategic aspects to favor just the purely pecuniary ones. The reality is that Western armed forces, whether from the United Kingdom or any other NATO country, face not only IEDs and insurgent infantry in the mountainous regions of the Middle East, but also may have to confront peer rivals equipped with huge armored forces. Russia itself has about 2,000 battle tanks (that is, not counting other armored vehicles, whether they are capable of shooting rounds or not). China increases that figure up to 6,900 (more than half are completely out of date, although they are embarking on a total remodeling of the Chinese People's Army in all its forces). NATO does not forget the challenges, hence the mission "Enhanced Forward Presence" in Poland and the Baltic Republics, in which Spain contributes a Tactical Group that includes 6 Leopardo 2A6 Main Battle Tanks, 14 Pizarro Infantry Fighting Vehicles, and other armored infantry transports.

Certainly, war is changing. We can't even imagine how technology will change the battlefield in the next decade. Sometimes, though, it is better not to get ahead of time. Taking all aspects into account, perhaps the best decision the UK Ministry of Defense could make would be to modernize its tank battalions to adapt them to the current environment, and thus maintain a balanced military with full operational capabilities. It is plausible to predict that the tank still has a journey in its great and long history on the battlefield, from the Somme, to the war of the future. Time (and money) will tell what ends up happening.
