arabs are unfortunately too lazy to dig trenches.  you had towns contested for longer than ugledar with basically zero defensive works except maybe a brick wall or perhaps some sandbags.   hts always had glownigger advisors from the first day when they were still the al nusra front.  that is no excuse nor legitimate cope, syria has advisors from a country currently engaged in the bigged conflict since ww2, and still doesnt have electronic warfare modules or dedicated drone units on their side. it all stinks of military old guard mold thinking all those drones are just a temporary fad and the good old tank will come out on top.
