You’re just going to insult someone for making a reasoned, informed reply to a comment?

There are many reasons someone might join the armed forces, and whether or not you are a conscientious objector, you might consider thinking before calling someone a war criminal without knowing what they actually did during their time in the military. Plenty of people went into combat zones without committing any war crimes.

Also, ad hominem attacks are dumb and you shouldn’t use them.
