I came across a,thread in the forum talking about it, based on what I understood the location of event is beside town called Taqa (incorrectly mentioned as Tarqa in forum) .
the beach name is Khor Rori (“Khor” is arabic for Estuary, Rori seems unknown ancient word ).
Today this beach is considered protected archaeological site with pre-historic ruins been excavated.

Long time before retirement from Royal Oman Air Force all Omani Strike Masters were in gray camo . one can be seen as gate keeper here in the gray camo: 23°33’41.3″N 58°22’24.7″E

What is those antenna under the radar dome ! , and there seems some dome structure forward main landing gear housing ?

My understanding its because of how the MBT HKS (Hard kill systems) works–Arena is my example-, they are almost like primitive reactive/reflex kind systems.
They implement constant-not scanning- monitoring of possible threat directions by basic radar projecting radiation beam/s of radio waves with Doppler effect . They actually more like a road traffic speed camera -the fixed type- .With a number of pre set role to initiate the reflex -ejecting a projectile-, these include mainly threat speed and direction. as soon the threat inters the radiation beam and its fast speed reflect its singture in clear shift in frequency of radio , all the computer has to do is monitor the frequency shift and if its indicate a possible fast target heading towards -direction of the threat is done simply through Doppler effect ,red and blue shift in light- the tank ,it tireger the charges associated with direction of the activated beam.
So the MBT HKS stay passive most of time waiting for threat to get into its beam with two main parameters to be watched :
-Speed (pre set to today mostly subsonic AT missiles)
-Direction of the threat (only reacts to ones heading directly towards the tank)
both can be easily calculated through Doppler effect in the reflected frequency .
as you can see by this system will not activate if the projectile if it was not headed towrds the tank it protect, and will not react to a passing by vehicle as its not in the speed limit.
This totally opposite to CIWS/SAM ,these are complicate systems with multipliable level of search/identify/track/control procedures requiring different kind radars and elements , needed very powerful computer systems to calculate fire solutions and continue to guide the missile or gun barrel towards the target until it distraction.

My extreme apology for my clumsy English

couple of videos I came across…

Sub-munitions

It not PAK air force and its not Sub-munitions
The video is showing A-10 GAU-30 30mm Gatling gun attack run during a support mission over Afghanistan .

What missiles do Syrians have that can shoot out to (13nm) 22.2 km?

If i may give my best guess about the missile that hit Turkish RF-4, I will say it’s Pantsyr S1E most probably the one that hit it, even it’s quoted 20 Km maximum range officially , we must consider that distance 22Km from the cost is not so far from 20 Km and some kilometers difference could attributed to accuracy of Turkish radar data (or just a political cover up). Pantsyr S1E is highly mobile system and even though it’s radar guided, the missile is radio controlled to fuse activation and the tracking radar uses extremely high frequencies , and due to the fact the system is new in the area the Turkish air force were not able to update there EW systems (RWR, ECM, etc) to it’s new working frequencies, or simply the systems were Optically guided .this why there was no alert was given about the presence of a threat in the area to pilots.
My apologies for the poor English.

More interesting though, is what i have read in ACIG site ! ,one of Iranian (imperial air force then) RF-4 manged to dodged four K-13’s (AA-2 atoll)fired from a soviet Mig-21SMT that was trying to shot it down over soviet territory, all RF-4E was doing seems was firing it’s photo flash cartridges and opps! the missile is lost.

Looking forward to see a photo of these cartridges.
