"Brazilian Army Pvt. Francisco de Paula of the Brazilian Expeditionary Force prepares to load a 105 mm M2A1 howitzer, shoving a shell into the breech of his gun with the inscription “A cobra está fumando" (The snake is smoking) during the Italian Campaign, WWII." - marinamaral

"The saying "the snake is smoking" comes from the brazilian doubt that the Allied Foces would need the help of Brazilian soldiers during the war. People used to say that was easier to see a snake smoking than Brazil joining the war. So when the expeditionary forces were called to arms they adopted that slogan "the snake is smoking"." - Deleted Account
