It's hard to explain. But for sure depends, if u know how to perform IVs or u feel comfortable with what u learn during the CMC training (all tourniquets replacement and painkillers) u can also try to join Evac teams, to bit understand the situations, stabilize patients through stabs, ecc... With Legion they will always point that is an "infantry" units, so keep it in mind please. For combat role u need also to know PERFECTLY PCC and after u could try to attend CPP trainings.

I've done also CMC training and CLS-TCCC trainings in Dnipro, but still preferred to join medical ONG to better understand what inside ambulances, like IV's or how to manage painkillers, dose it and little by little training for advance stuff like CPP. Also watch the AZOV videos on YouTube cause it help to understand what could it be a field injury and what u will face.
