"Every year, out of 84 thousand conscripts, only 3.5 thousand young people are actually drafted into the army - the rest fall out due to the applicable exceptions or they do not meet the health requirements.This could be representatives of technical, engineering or medical fields.
After three months of basic training, they would be released into reserve.
3.5 thousands are serving each year, 10 thousands disappear, and cannot be contacted. Amazing.
Drone operators with poor health would get only cheap Chinese drones with very short distance of flying. Therefore such drone operators should be very close to the enemy formations. This is very dangerous position to be - as soon as these drones start flying, enemy's artillery kills the drone operator. What an irony - volunteer with poor health would become drone operator and would be killed first.
