British army officers wore blue peaked caps as early as the Crimean War to distinguish themselves from enlisted men who wore the pillbox hat . The peaked caps were widely worn on campaign during the First and Second World Wars, until the more practical beret was popularised by generals like Bernard Montgomery . After the war, officers continued to wear khaki caps as part of the Number 2 dress uniform , but by the 1990s these had been phased out in favour of the dark blue and red caps previously worn with the Number 1 dress uniform .
Now stationed at G-5, Smoker found out that the Straw Hat Pirates had entered the New World, following them to the forbidden island Punk Hazard . Smoker then encountered the Shichibukai Trafalgar Law , who defeated him, took his heart, and switched him with Tashigi. The Marines then attempted to invade Caesar Clown 's lab, having found out about him experimenting on abducted children. However, they encountered and battled the Straw Hats, and Caesar arrived and easily defeated them, putting Smoker and Tashigi in a cage with the Straw Hats and Law.
