This is a retarded take.
Professional soldiers with a wife and kid tend to have knocked up their wife before or during their time as a professional soldier. There's a bit of an understanding on the wife's end that her husband is going to be doing military shit, along with (in the west) the safety net of the life and health insurance policies should anything bad happen. In the US if daddy soldier comes back in a body bag at least the kid is going to get a ton of benefits and have their education 100% paid for, among many other things.
Veteran or random rambo deciding to just go get involved in a conflict across the world while leaving his wife and kid behind is just selfish in this case. What exactly is he going to do? Is he going to stop the Russians?
He's going over to volunteer for a vastly outnumbered force against a professional military. Even if he kills 10 Russians, every single time he's out there he's risking himself to the detriment of his family and they get nothing for his death, not even the courtesy of a proper confirmation of death until this blows over, if even then.
Are you kidding me? You're telling me soldiers with families are exempt from war?
People went on multiple tours.
People sign up to the military when they have families but more commonly they stay in them despite forming families after a tour of duty or before one, even when they have the oppurtunity to leave.
Every single time a US soldier was risking his life in Iraq, it was for the general detriment of his familly. Even if the familly gets some money for it.
Now this guy has obviously done both, as a Canadian sniper in Afghanistan.
But I'd rather be choosing my battles than not.
Now are his choices in this case sound? No, fuck no. They are retarded, like you said he's not getting payed, the conflict has little direct incentive for him. But obviously he's some kind of war junkie/person who feels at home in conflict and/or really feels for the Ukranian side.
My point was that the individual choice is no worse (imo better) than being prodded to a war by some national military.
I mostly respect people who serve in effectively territorial guard units/home defense units (american national guard can apparently be sent to foreign wars so thats insane). These people serve their country in times of both military and civil emergencies but in most countries they can't be sent to war in a foreign country.
I'd rather be a mercenary than a professional soldier.
