This poster in the Ukrainian language reads: "Join the Red Cavalry".
I think is more appropriate to you this poster.
"Comrades Muslims! Under the green banner of of the Prophet you go conquer your steppe, your auls. The enemies of nation have taken away from you native fields. Today, under the red flag of the Workers 'and Peasants' Revolution, under the star of of the army of all the oppressed and working people - you to going from the east and west, north and south. In the saddles comrades, all into regiments of universal military training!"
