Blitzkrieg
Implementation of higher orders remained within limits that were determined by the training doctrine of an elite officer corps.
Delegation of authority to local commanders increased the tempo of operations, which had great influence on the success of German armies in the early war period. Seeckt, who believed in the Prussian tradition of mobility, developed the German army into a mobile force and advocated technical advances that would lead to a qualitative improvement of its forces and better coordination between motorized infantry, tanks, and planes.

Britain: The British Army took lessons from the successful infantry and artillery offensives on the Western Front in late 1918. To obtain the best co-operation between all arms, emphasis was placed on detailed planning, rigid control and adherence to orders. Mechanization of the army, as part of a combined-arms theory of war, was considered a means to avoid mass casualties and the indecisive nature of offensives. The four editions of Field Service Regulations that were published after 1918 held that only combined-arms operations could create enough fire power to enable mobility on a battlefield. That theory of war also emphasised consolidation and recommended caution against overconfidence and ruthless exploitation.
During the Sinai and Palestine campaign, operations involved some aspects of what would later be called blitzkrieg. The decisive Battle of Megiddo included concentration, surprise and speed. Success depended on attacking only in terrain favouring the movement of large formations around the battlefield and tactical improvements in the British artillery and infantry attack. General Edmund Allenby used infantry to attack the strong Ottoman front line in co-operation with supporting artillery, augmented by the guns of two destroyers. Through constant pressure by infantry and cavalry, two Ottoman armies in the Judean Hills were kept off-balance and virtually encircled during the Battles of Sharon and Nablus (Battle of Megiddo).
The British methods induced "strategic paralysis" among the Ottomans and led to their rapid and complete collapse. In an advance of 65 miles (105 km), captures were estimated to be "at least 25,000 prisoners and 260 guns". Liddell Hart considered that important aspects of the operation had been the extent to which Ottoman commanders were denied intelligence on the British preparations for the attack through British air superiority and air attacks on their headquarters and telephone exchanges, which paralyzed attempts to react to the rapidly-deteriorating situation.

France: Norman Stone detects early blitzkrieg operations in offensives by French Generals Charles Mangin and Marie-Eugène Debeney in 1918. However, French doctrine in the interwar years became defence-oriented. Colonel Charles de Gaulle advocated concentration of armor and airplanes. His opinions appeared in his 1934 book Vers l'Armée de métier ("Towards the Professional Army"). Like von Seeckt, de Gaulle concluded that France could no longer maintain the huge armies of conscripts and reservists that had fought the First World War, and he sought to use tanks, mechanized forces and aircraft to allow a smaller number of highly trained soldiers to have greater impact in battle. His views endeared him little to the French high command, but, according to historian Henrik Bering, were studied with great interest by Heinz Guderian.

Russia and Soviet Union: In 1916, General Alexei Brusilov had used surprise and infiltration tactics during the Brusilov Offensive. Later, Marshal Mikhail Tukhachevsky (1893–1937), Georgii Isserson (1898–1976) and other members of the Red Army developed a concept of deep battle from the experience of the Polish–Soviet War of 1919–1920. Those concepts would guide the Red Army doctrine throughout the Second World War. Realising the limitations of infantry and cavalry, Tukhachevsky advocated mechanized formations and the large-scale industrialisation that they required. Robert Watt (2008) wrote that blitzkrieg has little in common with Soviet deep battle. In 2002, H. P. Willmott had noted that deep battle contained two important differences from blitzkrieg by being a doctrine of total war, not of limited operations, and rejecting decisive battle in favour of several large simultaneous offensives.
The Reichswehr and the Red Army began a secret collaboration in the Soviet Union to evade the Treaty of Versailles occupational agent, the Inter-Allied Commission. In 1926 war games and tests began at Kazan and Lipetsk, in the Soviet Russia. The centers served to field-test aircraft and armored vehicles up to the battalion level and housed aerial- and armoured-warfare schools through which officers rotated.

Nazi Germany: After becoming Chancellor of Germany in 1933, Adolf Hitler ignored the provisions of the Treaty of Versailles. Within the Wehrmacht, which was established in 1935, the command for motorized armored forces was named the Panzerwaffe in 1936. The Luftwaffe, the German air force, was officially established in February 1935, and development began on ground-attack aircraft and doctrines. Hitler strongly supported the new strategy. He read Guderian's 1937 book Achtung – Panzer! and upon observing armored field exercises at Kummersdorf, he remarked, "That is what I want – and that is what I will have".

Guderian: Guderian summarized combined-arms tactics as the way to get the mobile and motorized armored divisions to work together and support each other to achieve decisive success. In his 1950 book, Panzer Leader, he wrote:

In this year, 1929, I became convinced that tanks working on their own or in conjunction with infantry could never achieve decisive importance. My historical studies, the exercises carried out in England and our own experience with mock-ups had persuaded me that the tanks would never be able to produce their full effect until the other weapons on whose support they must inevitably rely were brought up to their standard of speed and of cross-country performance. In such formation of all arms, the tanks must play primary role, the other weapons being subordinated to the requirements of the armor. It would be wrong to include tanks in infantry divisions; what was needed were armored divisions which would include all the supporting arms needed to allow the tanks to fight with full effect.
Guderian believed that developments in technology were required to support the theory, especially by equipping armored divisions, tanks foremost, with wireless communications. Guderian insisted in 1933 to the high command that every tank in the German armored force must be equipped with a radio. At the start of World War II, only the German Army was thus prepared with all tanks being "radio-equipped". That proved critical in early tank battles in which German tank commanders exploited the organizational advantage over the Allies that radio communication gave them.
All Allied armies would later copy that innovation. During the Polish campaign, the performance of armored troops, under the influence of Guderian's ideas, won over a number of skeptics who had initially expressed doubt about armored warfare, such as von Rundstedt and Rommel.

Rommel: According to David A. Grossman, by the Twelfth Battle of Isonzo (October–November 1917), while he was conducting a light-infantry operation, Rommel had perfected his maneuver-warfare principles, which were the very same ones that were applied during the blitzkrieg against France in 1940 and were repeated in the Coalition ground offensive against Iraq in the 1991 Gulf War. During the Battle of France and against his staff advisor's advice, Hitler ordered that everything should be completed in a few weeks. Fortunately for the Germans, Rommel and Guderian disobeyed the General Staff's orders (particularly those of General Paul Ludwig Ewald von Kleist) and forged ahead making quicker progress than anyone had expected, on the way "inventing the idea of Blitzkrieg".
It was Rommel who created the new archetype of Blitzkrieg by leading his division far ahead of flanking divisions. MacGregor and Williamson remark that Rommel's version of blitzkrieg displayed a significantly better understanding of combined-arms warfare than that of Guderian. General Hermann Hoth submitted an official report in July 1940 which declared that Rommel had "explored new paths in the command of Panzer divisions".

Methods of operations: 

Schwerpunkt: Schwerpunktprinzip was a heuristic device (conceptual tool or thinking formula) that was used in the German Army from the nineteenth century to make decisions from tactics to strategy about priority. Schwerpunkt has been translated as center of gravity, crucial, focal point and point of main effort. None of those forms is sufficient to describe the universal importance of the term and the concept of Schwerpunktprinzip. Every unit in the army, from the company to the supreme command, decided on a Schwerpunkt by schwerpunktbildung, as did the support services, which meant that commanders always knew what was the most important and why. The German army was trained to support the Schwerpunkt even when risks had to be taken elsewhere to support the point of main effort and to attack with overwhelming firepower. Schwerpunktbildung allowed the German Army to achieve superiority at the Schwerpunkt, whether attacking or defending, to turn local success at the Schwerpunkt into the progressive disorganisation of the opposing force and to create more opportunities to exploit that advantage even if the Germans were numerically and strategically inferior in general. In the 1930s, Guderian summarized that as Klotzen, nicht kleckern! ("Kick, don't spatter them!")
