In the terrible time when war was the order of the day for all generations, the Infantry was " taught" to the children of France with raw, direct, somewhat caricatural words like-us. But they were authentic and did not try to hide their patriotic vocation...-tick. As such, all weapons and subdivisions of weapons were described with the same "sobriety". Today, we smile about it. In the imaginations of the children of that time, familiar and disappeared faces would light up again when reading this alphabet..

Although asymmetry locally challenges the J.F.C. paradigm.Fuller's paradigm according to which military thought and training adapt to innovation, Squadron Leader Roméo Dubrail and Battalion Chiefs Antoine Mathey and Yann Queran show that this analysis is true in France from 1945 to the present day. Indeed, whether it was during the age of the atom or the age of NICTs, the technological breakthrough initiated a real revival of strategic and tactical thinking and, as a result, major changes in the training of the elite. Conversely, the descending phase of the atomic age showed a sclerosis of military thinking around the use of nuclear weapons.

France must now seek to trace the contours of the future major technological breakthrough, both through dual-use research and through research specific to armies, in order to derive intrinsic advantages in all fields, if it wishes to remain a major nation on the international scene.

While ergonomics is having an increasing impact on armament operations, some recent RETEXs have nevertheless revealed the lack of ergonomics of certain army equipment. While these shortcomings are true, it is also true that ergonomics suffers from its low profile and needs to be better integrated into the Army's capability process. The challenge is to improve the expression of ergonomic needs.

Whatever name we give it, "digital revolution", "digitalization", "digitalization", "digitalization", "digitalization", "digitalization", "digitalization", "digitalization data" of the world (for English datafication), "digital transition" or simply "digitization", sharing and processing of data over a network apply to all ‒ States as individuals, companies as organizations public ‒in all fields of human activity... ‒ of the most from the everyday to the most advanced professional applications. More that a technology is a phenomenon that underpins the functioning of our societies... and transforms them in depth; it is a whole way of life that changes with the technology. In this, perhaps, it is not abusive to speak of "revolution".

The Cahiers regularly devote some of their lines to Marshal Lyautey. In this year which marks the 90th anniversary of his official departure from Morocco, it seemed important to us to remember who this man was, a military leader, a political figure, a philosopher, who counted and still counts many admirers, but also many detractors. This homage will be paid through a series of articles for which our thanks go particularly to the Fondation Maréchal Lyautey and its president, Colonel (H) Pierre Geoffroy.[1].

(Re)read Foch! Today? What for?

General Gilles Bemelmans reminds us of what characterizes him: common sense, that of reality. At ground level, it is the case to say it. This aspect never disappears, even when he is in charge of the highest responsibilities.

To study the legacy of the Great War for contemporary infantry is to describe an unprecedented modernization between 1914 and 1918. It also means making a hyphen of nearly a century to show that beyond technical evolution, the foundations have endured and remain relevant. Above all, it means looking to the future to ensure that contemporary infantry is armed to meet the challenges that lie ahead.

According to the most widespread opinion, technology would be the decisive trump card in the fight. Victory would be the result of a valuable discovery, which would make victory inevitable. The decisive blow, the overthrow are attributed to such technological prowess. Commentators do not hesitate to invoke the superiority of such weapons, even if it means listing these weapons with mythical names (the Patriots, the Tomahawks...) to the general public. In the race for progress, technology has become a commonplace that we should not exegesis. Sometimes, the cause of the triumphant "good" is associated with its technological expression. However, this should be put into perspective, otherwise we risk falling into a kind of credulity with regard to science. Scientism has its limits. Even in military history.

While the military operations of Western armies have only recently become sustainable, their military tools will soon be able to carry out only short actions, because of the ever-increasing pressure on defence budgets and public opinion that has become very difficult to convince of the usefulness of long operations. It is from this observation that the concept of "rapid warfare/disengagement", which is increasingly in vogue across the Atlantic, has emerged. The author describes it for us, showing us its advantages, disadvantages and limits.

The increasing number of attacks in cyberspace in recent years, particularly involving major powers, raises questions about the role that digital capabilities could play in deterrence in the future. The aim of this article is to briefly recall the foundations of nuclear deterrence, to study the potential of digital technology in the field of deterrence, before analysing whether digital capabilities could play a role in the future.It is possible to envisage the implementation of cyber-deterrence in the face of cyber-attacks or, more generally, possibly as a complement to nuclear deterrence.
