The following study shows that PTSD, depression and anxiety present actual and urgent problem in military field. These disorders appear to be highly co-morbid that results in much more complicated treatment process and outcome. Service members of Georgian armed forces participate in various international peacekeeping operations on the regular basis, though there are no researches conducted so far to provide evidence for mental health problem prevalence in Georgian deployed military personnel.

Collection of the data took place during the period of 2014–2015 years after six months of service members returning from the international peacekeeping mission back to their homes. The sample for this research were represented by 2799 servicemen who actively engaged in ISAF peacekeeping missions. All of them were male, with average age: M=29.3 (SD=6.3). The data for the following research were collected using self-administered assessment measures, namely PCL-5 for PTSD screening and PHQ for depression and Anxiety and somatic complaints assessment.

PTSD appeared to be significantly predicted by range/level of anxiety and depression symptom urgency, nevertheless after joint/combine integration of these variables in one regressional equation, just symptoms of depression remained as statistically reliable explanatory factor for the significant percentage of the somatic symptom range variation.

It would be wise to recommend mental health care specialists particularly to bear in mind the possibility of co-existing depression and anxiety symptoms in patients with PTSD.
