There was a Russian troll here asking why I didn't leave earlier even though I knew this would happen, and whether I'm planning on bribing officials to avoid conscription. I already wrote the answers but the parent comment was flagged, so posting here:

1. Most people I know didn't believe Putin would suicidally start a large-scale invasion, despite potentially severe losses (~10k Russian soldiers killed so far in a week) and the complete destruction of Russian economy. Many thought US intelligence' warnings were a part of the information warfare for deterrence. We were wrong. Putin is actually this insane.

2. I registered where I'm staying locally and the military have my number / temp address if they need me. But the number of volunteers to fight WAY exceeds military capacity, so for now I'm staying in the rear and helping where I can make the most impact — by rallying donations, consulting IT volunteers on local map projects, and spreading the truth. I'm contemplating getting my wife and kids through the border but will stay in Ukraine myself, like other Ukrainian men.
