On 9 May, Iranian forces in Syria launched several rockets against Israel. The Israeli response was swift and included one of the largest air campaigns the region has seen.
However, attention soon turned to one single strike in particular, as the Israeli forces released a video clip shot by a missile taking out a Pantsir-S1 (SA-22 GREYHOUND). While it has earlier been reported that Pantsirs have been destroyed in Syria (a misidentified Mercedes truck a year ago comes to mind), this is the first confirmed instance I have seen.
The Pantsir is the short-range companion to Russia’s more famous long-range S-300/S-400 air defence missiles, and its role is to swat down any aircraft or air-launched weapons which manage to penetrate to close range where the longer-ranged systems are less capable. In line with the Russian marketing of the longer-ranged systems, the Pantsir is described as “near 100 % efficiency” and some western journalists have described it as showing how Russia’s “air defenses outpace America’s”. Needless to say, there are preciously little evidence to support Russia’s claims, and as the Israeli video is one of the rare documented encounters between the system and an airborne enemy it quickly generated considerable discussions.

On one hand, some questioned whether the system was a decoy, others whether it was operational, and some declared the whole Pantsir-family as being nothing but expensive trash. All in all, the short clip deserves further scrutiny.
It is clear that the radar is elevated and pointing backwards, as the U-shaped radar support is visible (blue). The weapons are pointing towards the rear, which is the transport position (though if the whole vehicle was rigged for transport, the radar would be lying flat facing upwards). The front of the truck corresponds with the Kamaz 6560 which is used by the most numerous Russian version (red).
Could it be a decoy? Parking out in the open on the tarmac and not making any attempt at covering the system certain seems to be begging to be destroyed. However, a crucial detail is visible in the video. A group of people are standing next to the vehicle, and seconds before the missile impact it one of them runs towards it.
Whether he was trying to save it or fire at the attacker is unsure, but in any case you would not run towards a decoy being fired upon. A brave act, but far too late.
Interestingly enough, images of the destroyed vehicle also appeared afterwards.
The picture matches the video as far as it is possible to tell. The truck is hit just aft of the cabin, the weapons are facing rearwards, and the radar is raised. The versions floating around on pro-Assad accounts often refer to the IAI Harop, a loitering UAV, while other sources often mention the Delilah loitering cruise missile (others still refer to the Spike NLOS, a very long range anti-tank missile). All three carry relatively small warheads consistent with the kind of damage visible in the picture. However, the only evidence in either direction I’ve seen is that the sight picture does seem to match the Delilah better than it does for the other two.
In any case, the exact weapon doesn’t really matter, as this was not a case of an Israeli wonder-weapon being able to crack the defences of the Pantsir. Instead, it is clear that poor training on the part of the Syrian air defences, coupled with the lack of a clear situational picture, spelt the end for the Pantsir. The latter comes as no surprise, considering the numerous Israeli strikes targeting the integrated air defence network operated by Syria, but as shown by Serbia during Operation Allied Force, it is possible to stay alive and at least constitute a force-in-being even if the individual units have to fight their own war. This however require basic skills and training which the Syrians clearly lacked in this case. The Pantsir had no job standing out in the open if it lacked missiles, and it never had any job being parked in such an open spot without camouflage (as a matter of fact, it can fire on the move, so parking out in the open even if camouflaged might not be the best option).

For the Russians getting the Pantsir knocked out was something of an embarrassment, and they have been quick to point out that it must have either been out of ammo or otherwise non-operational. While that seems to indeed have been the case, it should be noted that days after the strike, the Russian government made a U-turn with regards to supplying the advanced long-range S-300PMU-2 free-of-charge to Syria. The idea was floated after the Western cruise missile strikes, but is now apparently completely scrapped. Many sources attribute this to Israeli prime minister Netanyahu’s successful lobbying during his recent visit to Moscow, but one has to wonder if not the incompetency shown by the Syrians operating the Pantsir caused concerns about the international embarrassment a successful strike against the S-300 would cause for the Russian arms manufacturers. As such, taking out the Pantsir might indeed have had significant regional consequences, but it does not in any way prove the system itself either good or bad.
