Dear in-Christ list! I'll have the formal name of the icon for you shortly, as soon as I get a telephone call back. To cut through the nonsense, both icons are from the same podlinnik (or prototype). They do indeed depict Russian soldiers wearing World War I uniforms, and there are firearms present. It's a shame the inscrption line on either is not readable (at least on my monitor), because I would be happy to translate the inscription for you. I'm assuming that the inscription will say something like Manifestation of the Mother of God to . . . . on . . . . at . . . because that's the standard format.
I'm new to this list, but I am a scholar of icons, and happy to offer whatever meager insight I can provide.
