And now for the history of the development of the doctrine of deep battle. When Trotsky was replaced as commander of the Red Army by Frunze a discussion about how the Red Army would conduct future operations gathered speed. Basically in the initial stages there were two views: a) Svechin aruged that all future wars would be wars of attrition - on the basis that when nations fielded armies of several million men spread over several hundred or even thousand miles the only feasible strategy was one of gradually grinding them down since decisive victories could only be of local importance. b) those like Triandafillov and Tukhachevsky who argued that it would be possible to achieve strategically decisive victories even in modern total mobilisation types of conflict. As ever an accomodation was found to be possible in which the first phases of combat would be fluid and could be used to decisively shape the latter stages of the conflict, which would be attritional in nature. In the end Triandafillov, Tukhachevsky and Svechin came to agree that in between the tactical and strategic layers of conflict was a linking layer, called the operational layer. As time passed the smallest unit capable of operating independently on the Operational layer came to be the division. Basically the tactical layer was everything which happened at the sub-division level ( within direct fire and indirect (divisional ) fire range of the enemy front line ), the operational was everything which happened between the tactical and the strategic layers and the strategic layer basically began at the level where armies were being moved around. Sound vague? Well, it is. You have had lots of different attempts to clarify those differences but sometimes a little ambiguity is good since at different times the distance to the strategic layer varies based on the technical-tactical characteristics of the weapons systems - e.g. the onset of airpower increased the operational depth and pushed the strategic depth farther from the front line. So, the boundary between tactical, operational and strategic is fluid and very much based on the tactical-technical characteristics of the weapons systems available. So, a little ambiguity is good. One other way of thinking of the strategic depth was that area which lay in between the enemy's factories and training camps ( back in Germany ) and the beginnings of the support echelons for his front-line troops ( tank repair yards, supply dumps etc ). You had the front line trenches ( tactical ), you had the artillery, support troops, supply dumps, repair yards and railheads ( operational ) and then between those and the German border you had the strategic. ( obviously they didn't express it in terms of German forces. That's just me making the example easy.) So, what was the goal of the deep battle? Basically it comprised the Soviets co-ordinating multiple operations ( they could be concurrent or they could be consecutive, or some mix of the two ) over space and time in order to create a cascading deterioration in the strategic situation which, eventually, dislocates the enemy's entire strategic defensive arrangement and forces the enemy to transition from a stubborn, relatively static defence into a retreat - which the Soviets hoped to transition into a pursuit and rout with the attendant increase in casualties. In order to achieve this goal the Soviets parcelled out forces as follows: 1. The Division which undertook the tactical mission on the battlefield. 2. The Corps/Army ( eventually all Corps transitioned to Armies ) which undertook the operational mission in the operational direction. 3. The Front ( comprised of several Armies, let's say 4. 3 of these would be Rifle Armies while the 4th would be a Mechanised or Tank Army. The Front's mission would be to use its Armies to achieve operationally important breakthroughs and then unleash the Tank or Mechanised Corps in order to turn that successful operation into something strategically decisive. ) Again it is a little vague but, basically the Divisions fought like demons on the front lines. The Armies were responsible for using their subordinate divisions as pinning forces and identifying one as the breakthrough division. This division would break through its opposition and create a gap which would be widened by Army-level assets until such time as the Mechanised/Tank Corps could pass through the gap and race deep into the enemy rear in pursuit of operational objectives. At this point in time the Army would have achieved its operational level objective ( passing a Tank/Mechanised Corps into the enemy rear so it could capture the operational objective ). Now the Front would get in on the act. It would, once notified of the operational breach in the enemy line begin getting its exploitation force ( later called an Operational Manoeuvre Group ) moving and pass them through the gap in the line in a drive on distant strategic objectives which would be so vital to the enemy that taking them would dislocate the entire current defensive line and force it to withdraw. What were the problems with this concept in view of the technology of the 1920s? 1. You had to have artillery superiority in the tactical and operational zones in order to achieve the breakthrough and suppress enemy interdiction of the routes of advance. This is why the Soviet Union developed such a large artillery park AND also invested so much in long-range guns ( what we, in the west would view as Corps-level assets ). The need to ensure appropriate levels of artillery support for the various phases also explains much of the reason why the Soviets had such large artillery groupings at Army and Front level. 2. All this talk of sweeping advances is all well and good but one of the prime lessons of the First World War was that the defender could bring their reserves into action to close off a breach more rapidly than an attacker could bring their reserves into action ( across cratered ground ) to exploit it. Thus a means must be found to move the offensive reserves into action quickly ( APCs/IFVs/desantniki ) and also another means should be found to suppress the enemy reserves and prevent their movement ( it is for this reason that about half of any Soviet armoured formation ( including MBTs ) which was assigned a break-in or exploitation role would be assigned a primary recon mission - their job was not just to break through but to let higher HQs know where the enemy reserves were so those reserves could be fixed by artillery and airpower ). The means of suppressing the reserves were airpower and artillery. 3. RECON: If you were to pick the right portion of the front to attack and break through in you needed excellent recon. You also needed excellent recon into the enemy's operational depth so you could begin guessing where their reserves might be and could mount artillery, air or guerilla strikes on those reserves to fix them in place while you were passing the exploitation forces through. 4. Simultaneity. Really, when you look at the deep battle concept you see that for it to succeed the entire depth of the battlefield had to be engaged and suppressed simultaneously. This necessitated the development of longer-range artillery and airplanes capable of operating into the enemy's operative depth ( the Il-2 is the best example of this and very much a philosophical precursor of the Mi-24/28 --- although the Mi-24 was better because it could also carry troops, which the Il-2 couldn't ) as well as the Red Army fetish for airborne and special operations troops. When WW2 began the Red Army had more airborne troops available than all other armies in the world combined. That didn't last long of course but it does go to show you the importance they attached to airborne troops - why? Simple, drop 1,000 airborne troops on a bridge and you can stop enemy reserves using it AND ensure it is still present when your own mechanised troops reach it in order to pass into the enemy's strategic depth. So, what might a deep battle set up look like? 1. RECON, RECON, RECON. Find and ID every enemy formation possible to a depth of at least 50 km. 2. Assign guerillas and paratroops multiple LOC, communications and HQ targets throughout the enemy operational depth with a view to disrupting C3 and also holding chokepoint bridges/roads etc. 3. Army-level artillery strikes at enemy operational reserves. Airstrikes at enemy operational reserves. 4. Airstrikes and artillery strikes on enemy tactical reserves. 5. Massive firestrikes on selected portions of the enemy front, ideally blasting several holes through the front in front of major road nets ( running at 90 degrees to the front, the Soviets aren't interested in anything paralleling the front quite yet ). 6. Infantry units advance and move through the gaps in the enemy line, turning left and right as they pass through the enemy line in order to secure and widen the shoulders ( to ensure they are wide enough to allow firstly divisional and then later Army and Front level assets to pass through ) whilse still driving deeper into the enemy's tactical depth. Ideally they break through the enemy's tactical depth using just divisional-level assets. If necessary though Army-level independent sub-units could be used to complete the divisional breakthrough into the operational depth ( better to use independent sub-units than to have the Army Mechanised Corps bogged down in the tactical zone ). 7. Once the Rifle Division had complieted the tactical mission ( breaking into the operational depth ) the Army level assets would pass through and conduct the operational mission in the operational direction ( towards the operational objective ). As those units advanced they would seek to bypass opposition, using their preponderance of recon assets to ID and call airstrikes and firestrikes on those positions. Throughout the whole of parts 6 and 7 airstrikes and firestrikes on enemy reserves in the tactical and operational depth would have continued in order to fix enemy forces in place. IN addition neighbouring fronts would be expected to pin the enemy forces and reserves facing them through a combination of pinning attacks, maskirovka and deep strikes by airpower and artillery. 8. Once the Operational breach had been verified the Strategic Direction would have committed its independent sub-units to ensure the survival of the breach and its Strategic Reserve/Operational Manoeuvre Group in order to drive into the enemy's strategic depth. There was a recognition that this would draw in the enemy's strategic reserve and that defeating this strategic reserve would probably necessitate at least one huge meeting engagement between the OMG and the enemy's mobile strategic reserve. Prokhorovka was an example of the Soviets committing a portion of their strategic reserve to the operational level in order to avoid the Germans in the southern axis of Kursk breaking through into the Soviet operational depth. Why was this? Simple, they knew nothing they had ( short of a strategic level Tank Army ) at the operational level would stop the Germans so they committed 5th GTA in order to stop the Germans. While its goal and level were different this sort of meeting engagement was what the Soviets recognised would happen when strategic reserves met. Their view, of course, was that even if their opponent could stop one such breach in this way they'd just unleash another planned offensive and so on and so forth until, eventually, the enemy strategic reserve would be so worn out and/or dislocated that they'd get a strategically decisive breakthrough. This was, largely, their plan at Bagration - which, together with the Manchurian offensive - comprises the acme of deep battle in WW2. Defence in Depth is basically setting up in order to avoid being defeated by the offensive portion of the deep battle doctrine and involves doing everything you can to avoid the initial breakthrough, avoid having your reserves ID'ed and pinned and to stop enemy exploitation forces without being destroyed yourself. Manstein's "back hand" at Kharkov in '42 is an excellent example of this. Obviously the above is only a very basic overview of a very complex topic but this isn't a book or a presentation at a War College so please judge it in that light. Next: The importance of echeloning and the myth of the absence of reserves in deep battle.
