What do you speculate is the cause?
Judging by the amount and color of the smoke and the fact there are at least three similar vehicles smoking simultaneously near a military base, my guess is that it is a military excercise, and the smoke is for concealment.
You're right, it's probably false smoke for exercise. They need a little more smoke to conceal something. I've seen an black smoke close to this area (I've lost the location).
Have you noticed how the city of Grozny is totally destroyed ? A lot of civilian building are demolished. This view can help you to understand how the Chechnya war is violent for Chechens.
It is horrific. I hadn't really looked closely until you pointed it out. It looks like virtually every building surrounding this military base has extensive damage, I imagine as a result of sniper supression.
Here are the coordinates to another of the smoking vehicles. If you follow the tire tracks back across the open field, it looks like it originated near the one you posted.
