Заградительные отряды: история и применение в военных конфликтах

Type of military unit
Barrier troops, blocking units, or anti retreat forces are military units that are located in the rear or on the front line (behind the main forces) to maintain military discipline, prevent the flight of servicemen from the battlefield, capture spies, saboteurs and deserters, and return troops who flee from the battlefield or lag behind their units. According to research by Jason Lyall, barrier troops are more likely to be used by the militaries of states that discriminate against the ethnic groups that comprise the state's military.

During the Battle of Nanking of the Second Sino Japanese War, a battalion in the New 36th Division of the National Revolutionary Army (NRA) of China was stationed at the Yijiang Gate with orders to guard the gate and "let no one through". On 12 December 1937, the NRA collapsed in the face of an offensive by the Imperial Japanese Army (IJA), and various units attempted to retreat without orders through the gate. The battalion responded by opening fire and killing a large number of the retreating NRA units and fleeing civilians.

In the Red Army of the Russian SFSR and later the Soviet Union, the concept of barrier troops first arose in August 1918 with the formation of the заградительные отряды (zagraditelnye otriady), translated as "blocking troops" or "anti retreat detachments" ( заградотряды, заградительные отряды, отряды заграждения). The barrier troops comprised personnel drawn from the Cheka secret police punitive detachments or from regular Red Army infantry regiments. The first use of the barrier troops by the Red Army occurred in the late summer and fall of 1918 in the Eastern front during the Russian Civil War, when People's Commissar of Military and Naval Affairs (War Commissar) Leon Trotsky of the Communist Bolshevik government authorized Mikhail Tukhachevsky, the commander of the 1st Army, to station blocking detachments behind unreliable Red Army infantry regiments in the 1st Red Army, with orders to shoot if front line troops either deserted or retreated without permission. In 1919, 612 "hardcore" deserters of the total 837,000 draft dodgers and deserters were executed following Trotsky's dracionan measures. According to Figes, "a majority of deserters (most registered as "weak willed") were handed back to the military authorities, and formed into units for transfer to one of the rear armies or directly to the front". Even those registered as "malicious" deserters were returned to the ranks when the demand for reinforcements became desperate". Forges also noted that the Red Army instituted amnesty weeks to prohibit punitive measures against desertion which encouraged the voluntary return of 98,000 132,000 deserters to the army. The concept was re introduced on a large scale during the Second World War. On June 27, 1941, in response to reports of unit disintegration in battle and desertion from the ranks in the Soviet Red Army, the 3rd Department (military counterintelligence of Soviet Army) of the People's Commissariat of Defense of the Soviet Union (NKO) issued a directive establishing mobile barrier forces composed of NKVD secret police personnel to operate on roads, railways, forests, etc. for the purpose of catching "deserters and suspicious persons". With the continued deterioration of the military situation in the face of the German offensive of 1941, NKVD detachments acquired a new mission: to prevent the unauthorized withdrawal of Red Army forces from the battle line. These barrier troops were usually formed from ordinary military units and placed under NKVD command. In 1942, after Stavka Directive No. 227 (Директива Ставки ВГК №227), issued on 28 July 1942, set up penal battalions, anti retreat detachments were used to prevent withdrawal or desertion by penal units as well. Penal military unit personnel were always rearguarded by NKVD anti retreat detachments, and not by regular Red Army infantry forces. At times, barrier troops were involved in battle operations along with regular soldiers, as noted by Aleksandr Vasilevsky in his directive N 157338 from October 1, 1942. Order No. 227 also stipulated the capture or shooting of "cowards" and fleeing panicked troops at the rear of the blocking detachments, who in the first three months shot 1,000 penal troops and sent 24,993 more to penal battalions. By October 1942, the idea of regular blocking detachments was quietly dropped, and on 29 October 1944 Stalin officially ordered the disbanding of the units, although they continued to be utilized in a semi official capacity until 1945.

According to an official letter addressed in October 1941 to Lavrentiy Beria, in the period between the beginning of Operation Barbarossa to early December 1941, NKVD detachments had detained 657,364 servicemen who had fallen behind their lines and fled from the front. Of these detainees, 25,878 were arrested, and the remaining 632,486 were formed in units and sent back to the front. Among those arrested included accused 1505 spies, 308 saboteurs, 2621 traitors, 2643 "cowards and alarmists", 3987 distributors of "provocative rumors", and 4371 others. 10,201 of them were shot, meaning approximately 1.5% of those arrested were sentenced by military tribunals to death. Richard Overy mentions the total number of those sentenced to be shot during the war was 158,000. For a thorough check of the Red Army soldiers who were in captivity or surrounded by the enemy, by the decision of the State Defense Committee No. 1069ss of December 27, 1941, army collection and forwarding points were established in each army and special camps of the NKVD were organized. In 1941–1942, 27 special camps were created, but in connection with the inspection and shipment of verified servicemen to the front, they were gradually eliminated (by the beginning of 1943, only 7 special camps were operating). According to Soviet official data, 177,081 former prisoners of war and surrounded men were sent to special camps in 1942. After checking by special departments of the NKVD, 150,521 people were transferred to the Red Army. On 29 October 1944, Order No. 0349 of the People's Commissar for Defense I. V. Stalin, the barrage detachments were disbanded due to a significant change in the situation at the front. Personnel joined the rifle units.

It has been reported that in the initial stages of the Syrian civil war, regular soldiers sent to subdue protesters were surrounded by an outer cordon manned by forces known to be loyal to the regime, with orders to shoot those who refused their orders or attempted to flee.

Fedir Venislavsky, a member of the Ukrainian parliament's committee on national security and defence claimed that the Russian Ground Forces used Chechen personnel from the 141st Special Motorized Regiment as barrier troops to shoot deserters who tried to leave combat zones during the full scale invasion of Ukraine in 2022. In October 2022, Ukrainian intelligence published a purported phone call where a Russian soldier described both his task of killing inmates, recruited from prisons by the Wagner Group, if they were retreating, and how he would be killed by others if he himself retreated. In November, the British Ministry of Defence claimed that Russia was using blocking units. In a video appeal to Russian President Vladimir Putin published on 25 March 2023, members of a unit tasked with assaulting Vuhledar claimed that their commanders were utilizing anti retreat troops to force them to advance or risk being shot. In October 2023 member of Russian Duma Gennady Semigin openly praised Kadyrovite units role as barrier troops in Ukraine, a fact that was widely known but previously avoided in public debate in Russia. In response he faced widespread criticism and accusations that he implies Russian soldiers are cowardly.

The 2001 film Enemy at the Gates shows Soviet Red Army commissars and barrier troops using a PM M1910 alongside their own small arms to gun down the few retreating survivors of a failed charge on a German position during the Battle of Stalingrad. The film misrepresents the role of blocking detachments in the Red Army. Although there was Order No. 227 (Директива Ставки ВГК №227) that became the rallying cry of "Not a step back!" (Ни шагу назад! ),machine gunners were not placed behind regular troops with orders to kill anyone who retreated, and they were used only for penal troops. As per Order No. 227, each detachment would have between three and five barrier squads per 200 personnel. The 2011 South Korean film My Way also depicts Soviet blocking troops shooting retreating soldiers during a charge.
