The Syrian Republican Guard (SRG), also known as the Presidential Guard, was an elite 25,000 man praetorian guard unit in the Syrian Army prior to the fall of the Assad regime, and was reportedly at a corps size with around 60,000 guardsmen. It was composed of two mechanized divisions with its main purpose to protect the capital of Syria, Damascus, from any foreign or domestic threats. The Republican Guard was the only Syrian military unit allowed within the capital before the civil war. It was designed to defend the President as well as the major presidential and strategic institutions, including the presidential palaces.
The Deir ez-Zor Governorate campaign of the Syrian civil war consists of several battles and offensives fought across the governorate of Syria:
The 25th Special Mission Forces Division, colloquially known by their former name Tiger Forces, is an elite special forces unit, that was part of the Syrian Army under the charge of the commander Major General Saleh Abdullah. It was formed in late 2013 and functioned primarily as an offensive unit in the Syrian Civil War. It had been described as a "hot commodity for any government offensive", but their relatively small numbers made it difficult to deploy them to multiple fronts at once.
The Palmyra offensive was a military operation of the Syrian Arab Army, supported by Russian airstrikes, to recapture from the Islamic State the city of Tadmur, which was strategically important for both forces due to its position in central Syria. The city was fully recaptured on 27 March.
The Special Operations Forces of the Armed Forces of the Russian Federation, commonly known as the Special Operations Forces, are strategic-level special forces under the Special Operations Forces Command of the General Staff of the Armed Forces of the Russian Federation. It is also a structural and an independent unit of the Armed Forces.
The Battle of al-Qaryatayn (2016) was a military operation launched by Syrian government forces, supported by Russian airstrikes, to recapture the town of Al-Qaryatayn from the Islamic State of Iraq and the Levant. The town lies in a junction that connects the Iraqi border with Palmyra and from Palmyra through to Damascus; it fell to ISIL during the previous Battle of Al-Qaryatayn.
The September 2016 Deir ez-Zor air raid was a series of 37 U.S.-led Coalition airstrikes near the Deir ez-Zor Airport in eastern Syria on 17 September 2016, lasting from 3:55 p.m. to 4:56 p.m. Damascus time in which Syrian Arab Army (SAA) soldiers were killed conducting operations against the Islamic State. Russia reported that at least 62 SAA soldiers were killed, while the Syrian Observatory for Human Rights (SOHR) said at least 80 were killed and 120 wounded. The United States said that the intended target was Islamic State militants and that the attack on Syrian soldiers was due to a misidentification of ground forces while the Syrian and Russian governments claimed that it was an intentional attack against Syrian troops. The attack triggered "a diplomatic firestorm" with Russia calling an emergency United Nations Security Council meeting. Later, the Syrian government called off a ceasefire that had been the result of months of intense diplomatic efforts by the U.S. and Russian governments.
The Palmyra offensive in December 2016 was a military operation launched by the military of ISIL which led to the re-capture of the ancient city of Palmyra, and an unsuccessful ISIL attack on the Tiyas T-4 Airbase to the west of the city. ISIL previously controlled the city from May 2015 until March 2016.
The Military Security Shield Forces, also called the Military Intelligence Shield Force or simply Military Shield, was a pro-government militia involved in the Syrian Civil War that was affiliated with the Military Intelligence Directorate.

The ISIL siege of the city lasted for almost 3 years and 2 months, after which the Syrian Army launched a successful offensive that fully recaptured the city nine weeks later.
The Syrian Desert campaign was a large-scale military operation of the Syrian Army that initially started along the highway from Damascus to the border with Iraq against rebel forces during the Syrian civil war. Its first intended goal was to capture both the highway and the al-Tanf border crossing, thus securing the Damascus countryside from a potential rebel attack. Later, multiple other fronts were opened as part of the operation throughout the desert, as well as operation "Grand Dawn" against ISIL with the aim of reopening the Damascus-Palmyra highway and preparing for an offensive towards Deir ez-Zor.
The Deir ez-Zor campaign, codenamed the al-Jazeera Storm campaign, was a military operation launched by the Syrian Democratic Forces (SDF) against the Islamic State of Iraq and the Levant (ISIL) in Syria's Deir ez-Zor Governorate in 2017 during the Syrian Civil War with the goal of capturing territory in eastern Syria, particularly east and north of the Euphrates river. The U.S.-led Combined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) anti-ISIL coalition provided extensive air support while SDF personnel composed the majority of the ground forces; OIR special forces and artillery units were also involved in the campaign.
