What is the flag which is half blue and half red? I looked up Chechnya and it is half green and half red.
“What is the flag which is half blue and half red?”
The Donetsk People’s Republic’s flag is Red, Blue and Black. The black might blend in to the background, or be omitted in some markings, that are not themselves flags. Luhansk People’s Republic’s flag is Red, Blue and White, so the same shorthand might apply to some identifying marking.
It’s not blue/red, but white/blue/red i.e. Russia
