Military In the Middle East 
I think that the Chaimite is equipped not with an ATGM launcher, but with an MBRL, in the neighborhood of 130-140mm caliber, like the Chinese Type 63 or the Russian BM-14. Note that the launcher appears to have been fitted on the hull roof behind the turret.
I was thinking about an MRl at first like the BM-14 but I never seen a Type 63 or BM-14 in such a configuration, the device is composed of 10 rounds, probably a field modification. Hope we will see that Chaimite again in a higher definition photo! I will add the fact it may be an MRL in the photo caption.
The way I see it, they’ve left some tubes empty, therefore at least the upper bank holds about 7 rounds in individual tubes. Can’t say for sure how many tubes there are in the lower bank. I agree we’ll need higher-def photos to be certain.
