Here's an overwiew of most recent conventional conflict involving a lot of T-72's.
Georgian side:
In 2008 all the T-72(AV/B)'s had K-1, out of total 65 georgian tanks, 15 were destroyed in combat, 20 were detonated after the conflict and 30 were taken as trophies. Out of the 15 tanks lost in combat five had their turret removed. 1 due to airstrike, 1 due to being abandoned and then detonated from inside, 3 due to RPG hits.
Russian side:
A total of three tanks were lost. T-72B(M) armed with K-5 Era which expended all of its amunition and was abandoned after being damaged by and RPG (no turret loss). T-62M, damaged by an RPG - turret kept (perhaps not relevant to this). T-72B (K-1 ERA), ambushed and struck by an RPG which cased ammo detonation.
All in all, out of all 17 combat lost tanks only 4 lost their turret in direct combat. https://sites.google.com/site/afivedaywar/Home/rutanklosses
