Early in the morning of January 6, Russian radars stationed around Latakia, Syria detected no less than thirteen kamikaze drones approaching. Ten of the explosive-laden unmanned vehicles streaked towards Hmeimim airbase, while three others swooped towards the Russian naval base at Tartus. Just a week earlier, Hmeimim had sustained a mortar attack that killed two personnel and likely damaged several aircraft .
According to Moscow, electronic-warfare assets allowed them to take control of six of the drones. The remaining seven were blasted out of the sky by Pantsir-S antiaircraft vehicles, which combine two rapid firing thirty-millimeter autocannons with a twelve surface-to-air missiles (SAMs).
A poster presented at a Russian arms expo claims to detail additional activity by Russian military Pantsirs in Syria, including the destruction of a number of drones around the naval base of Tartus: a Turkish Bayraktar drone in May, three Israeli Heron drones between April and July, and on May 27 an RQ-21A Blackjack, a roughly one-hundred-pound recon drone used by the U.S. Navy and Marine Corps. It also lists intercepts of three unguided rockets around Hmeimim airbase—with the Russian government claiming at least two more rocket intercepts in December 2017.

A Syrian Pantsir is alleged to have shot down a Turkish RF-4 Phantom reconnaissance jet in 2012, though it is also possible that a longer-range missile system was responsible. Pantsirs have also been spotted in territory held by Russian-backed separatists in eastern Ukraine.
The Pantsir (“Armor” or “Carapace”), which is also known by the NATO codename SA-22 Greyhound, is descended from a line of Soviet-era weapons meant to protect tank battalions from air attack, starting with deadly ZSU-23-4 “Shilka,” which was based on the chassis of a PT-76 amphibious tank . In contrast to preceding self-propelled flak guns, the Shilka introduced an onboard radar to guide the four rapid-firing twenty-three-millimeter cannons in its turret, allowing it to rip low-flying jets and helicopters to shreds with little forewarning. In one action during the Yom Kippur War, Egyptian Shilkas destroyed three low-flying Israeli Phantom jets on an air-defense suppression mission, and crippled two more.
While the Shilka remain in service across the world, the type was succeeded in the 1980s by smaller production run of more sophisticated 2K22 Tunguska (SA-19) vehicles, which swapped the quad guns for twin thirty-millimeter cannons—research had shown fewer, larger shells were more likely to down a plane than many small ones—and added on better radar and eight surface-to-air missiles, dramatically enlarging the system’s engagement range. This extra firepower was hoped to suffice for defeating NATO’s then-new armored A-10 Thunderbolt attack jets and Apache helicopter gunships.
In the 1990s, Russia began working on a Tunguska successor, swapping out the tracked, armored chassis for a truck body and increasing the missile load to twelve. While the armored Tunguska was suitable for accompanying tanks over rough terrain on the frontline, the idea was to make a cheaper but faster road-mobile system suitable for rear-area point-defense duty, including protection of long-range SAM batteries from incoming antiradar missiles and low-flying aircraft.
This Pantsir has gone through many variations since the first prototype debuted in 1995, with varying truck chassis and radar configurations. The most prevalent model in Russian service uses a Kamaz 6560 truck and has a crew of three. A Pantsir can operate independently, or an entire battery can be slaved to control of a command post or a more powerful radar unit, from which the vehicles can receive firing orders.
The antiaircraft system can detect approaching aircraft up to around twenty-two miles away using its Passive Electronically Scanned Array search radar. This allows it to cue its shorter-range but more precise engagement radar to begin locking onto a target from fifteen miles away—a process that can be accomplished in just six seconds. Additionally, the Pantsir has an electro-optical tracking turret with multiple imaging systems including a thermal channel as a backup sensor, particularly if jamming impairs the radar’s performance.
Once a targeting solution is acquired, the Pantsir can ripple-fire up to four missiles at two or three different targets at the same time, with just 1.5 seconds between each launch. A total of twelve are slung in launch containers on either side of the turret, and they can reach targets up to twelve miles away, and between near ground-level and fifty thousand feet high. The 57E6 missiles don’t have any onboard guidance systems, but instead continually receive targeting data via radio from the launch vehicle until they detonate near the target while soaring at Mach 3, supposedly with an estimated 70 percent hit probability.
If the missiles don’t do the trick, the Pantsir can engage incoming targets with its rapid-fire thirty-millimeter cannons housed in its rotating gun turret. The 2A38M cannons can rip out up to forty rounds per second each—two or three times the rate of fire of most machine guns—and can hit aerial targets up to two miles distant.
