Here is a tractor vehicle for anti-tank gun, but I cannot identify this one...

It's not ATG, it's AT-L, that stands for Light Artillery Tractor...
Not much info on wikipedia, though: http://en.wikipedia.org/wiki/AT-L
There's more on it at Jane's: http://articles.janes.com/articles/Janes-Military-Vehicles-and-Logistics/AT-L-Light-Tracked-Artillery-Tractor-Russia-and-the-CIS.html
and an article in french: http://www.armyrecognition.com/v_hicules_blind_s_artillerie_russie/at-l_artillery_tractor_tracked_vehicle_at-l_at-lm_russian_army_russia_description_pictures.html
A video of it at youtube:
