This is a re-post different source but the hatches were open an the laser system is shut off in that case. Someone said that the officer lost his head, and someone else said the bailing crew lost an arm - I couldn’t see either.
Ill trained crew - stationary too long, hatches open in combat zone, etc.
Crew likely was used to T-60s or T-70s which would have been a fatal hit and was reacting to that.
That the video cuts off after the hit and that there was no smoke coming from the gun barrel indicates no penetration and the tank may have returned fire, obliterating the TOW I crew.
Normal reaction time from TOW detection by tank to tank response is like 2-5 seconds - EOL TOW crew.
Much appreciated. Learned something new from your post.
Most likely ... T-90 is a new addition to Syrian armor, two months or so, and Syrian army for the most part does not suffer from extra competence yet. ISIS capture of Khanaser three days demonstrates serious problems on higher levels than a tank crew.
Very, very few tankers have experience with a penetrating anti-tank missile. Death is not a learning experience.
Closed breach is normal = no smoke from muzzle.
