Head strong, rebel at heart, smart mouth, loves big guns, makes his own cigars, and has an out dated knight in shining armor complex about sums up Gunnery Sergeant Gerico Kai. He has been busted down in rank twice for insubordination. If it wasn’t for his talent with heavy firepower and the shortage of soldiers, he would have been court-martialed right out of boot camp. The only person that can usually talk some sense into him is his younger sister Racheal. Since their parents death the two have been inseparable, he plays her overprotective big brother, and she cuts down on the number of his less than wise choices, which works out for the whole unit.
