MOS 999: What It Means and Why It Appears in “Rezerv+”
What Does MOS 999 Mean?
The Ministry of Defence clarified that MOS (Military Occupational Specialty) 999 is a specialty assigned to persons liable for military service who have not undergone military service or training camps. The norm is defined in the Ministry of Defence Order dated 07.09.2020 No. 317 based on Article 39 of the Law of Ukraine “On Military Duty and Military Service.”
This allows the state to estimate the number of persons liable for military service who need to undergo a basic general military training course in the event of conscription for military service during mobilization in a special period.
Why Does MOS 999 Appear?
By design, such a MOS should have appeared for those who did not undergo military service or training camps.
But in practice, we see a situation where the MOS in the employee’s military ID is present, but MOS 999 appears in “Rezerv+”. For some reason, the MOS was not entered into “Rezerv+”. In this case, MOS 999 was pulled up automatically.
This conclusion is prompted by the fact that this inscription means: the register has no information about your military occupational specialty.
At the same time, there are cases when the MOS was indicated in “Rezerv+” as well, but changed to 999 (usually to 999097).
Is It Necessary to Contact the TCC?
In the letter of the Main Personnel Department of the General Staff of the Armed Forces of Ukraine dated 19.09.2025 No. 321/VyhZP/266, it was noted that the presence of the mark “MOS 999. Requires basic general military training” in the “Rezerv+” application does not require the user to take any action. That is, there is no need to contact the TCC (Territorial Recruitment Center).
In other cases, we have a situation where the MOS in the paper military registration document (MRD) and “Rezerv ID” differ. In such a situation, it is still better for the employee to find out in the TCC why there are discrepancies. In fact, sometimes it’s just a human factor and operator errors.
Therefore, if an employee has discrepancies in the paper MRD and “Rezerv ID”, they should contact the TCC to update the information. The employer may hand the employee a notification about the need to update the MRD.
But truthfully, given the December innovations and the fact that today for persons registered in the TCC, only the electronic military registration document is valid, and the old MRDs are valid, but on the condition that their data do not contradict the data of the “Oberih” register, one could also not do this.
