Young men from the Caucasus (Dagestan in particular) have been complaining to the government that the army won't accept them as conscripts. While the army has been complaining of rampant draft dodging ever since the Soviet Union collapsed in 1991, they also have reasons for not wanting recruits from the Caucasus. Even before 1991, the Russian dominated army warned company (units of about a hundred troops) commanders to not allow more than ten Chechens (Chechnya is adjacent to Dagestan) in their unit. Experience had shown that ten or more Chechens (or other men from the Caucasus) would form a very tight, tough and disciplined clique that would prey on the other troops in the company, and cause all manner of discipline and crime problems. If you find yourself with more than ten Chechens, try and transfer some of them out.
While the Chechens were the worst in this respect, the other Caucasus nationalities came close. But these days, the young men want to join the army, and get a few years military experience, so they can qualify to become a "contract" soldier. These troops are paid a lot more, and are considered "professional troops." Commanders actually prefer contract soldiers from the Caucasus, although many will admit that it's still not wise to have more than ten of them in an infantry company.
