molotovs should be chemically ignited, a burning rag in a bottle will give your position away and likely light yourself on fire….
just soak a paper bag in a solution of [redacted] and let it dry, then add some [redacted] to the fuel in the bottle, place the bottle in the paper bag immediately before throwing it (arming it, sorta).
(make sure to rinse the bottle off and it’s dry and sealed extra well… like a cap then tape… and leave a little air at the top).
this was the original cocktail used in the Winter War against the Russians and General Molotov… also used by Jews against the nazis in the Battle of Warsaw… (they would sneak out of the ghetto and siphon gas from nazi vehicles).
(also used by nazi soldiers towards the end of the war)
tl;dr sticking a rag in the end of an open bottle, lighting and throwing it is stupid and a psyop….
