I'm glad to learn that some Ukrainian operators are able to target behind-the-lines Russian assets. The issue isn't so much insertion as exfiltration afterward. Beforehand, Russian military personnel will be careless, clueless, and often drunk. But after an attack - even a modest one that takes out only three helicopters - everyone will be scrambling to capture the team that inflicted the humiliation. And that means that exfil becomes difficult and dangerous. Let's hope the Ukrainian operators have sufficient support to give them a better than fighting chance of disappearing from the area of exploitation.
