You don't shoot in this war, infantry rarely even gets to positions due to frontline being overrun by drones. When you get there you just sit tight and fucking pray that nobody sees your position and report back where you seen or heard something. For the next two weeks or months. Depends on weather and other factors. Also lower height and weight is a must in assault forces, trenches are extremely fucking tight for normal sized people, r*ssian ones are extremely shallow sometimes.
Anyway, it's not hard to learn to pilot an fpv, it's hard to find technically inclined people that understand or want to understand radio and shit.
C'est la vie.
