Aim:
to establish the features of resilience, hardiness and social support in combatants with non-psychotic mental disorders who have suffered from COVID-19 in a comparative aspect.

Material and methods:
252 male combatants with non-psychotic mental disorders who suffered from COVID-19 were clinically examined using Connor–Davidson resilience scale-10, Brief Hardiness Scale and MSPSS.

Results:
in combatants with non-psychotic mental disorders that have suffered from COVID-19 were found lower levels resilience: 18.08±10.06 points vs 23.41±8.80 points (p<0.0001); hardiness: 12.28±4.20 points vs 15.67±6.88 points (p<0.001) and his components: commitment: 3.50±1.81 points vs 4.89±2.76 points (p<0.0001), control: 4.44±1.70 points vs 5.38±2.40 points (p <0.01) and challenge: 4.33±1.79 points vs 5.40±2.42 points (p<0.001); social support: 11.63±4.29 points vs 14.68±4.62 points (p<0.0001) and his components: family support: 3.85±1.54 points vs 4.95±1.58 points (p<0.0001), friends support: 3.95±1.48 points vs 5.00±1.77 points (p<0.0001) and significant other support: 3.83±1.51 points vs 4.73±1.53 points (p<0.0001). Among combatants with non-psychotic mental disorders who did not suffer from COVID-19, people with average and high levels of resilience, moderate resilience and a high level of social support predominated, and among combatants who recovered from COVID-19, people with low resilience, hardiness and social support.

Conclusions:
Combatants with non-psychotic mental disorders are characterized by a low level of resilience and hardiness, as well as a moderate level of social support, significantly worse in combatants that have suffered from COVID-19.
