When the Katipuneros had expanded to more than a hundred members, Bonifacio divided the members into three grades: the "Katipon" (literally: Associate) which is the lowest rank, the "Kawal" (soldier), and the "Bayani" (Hero or Patriot). In the meeting of the society, "Katipon" wore a black hood with a triangle of white ribbon having the letters ""Z. Ll. B."", corresponding to the roman ""A. N. B."", meaning "Anak ng̃ Bayan" (Son of the People, see below). "Kawal" wore a green hood with a triangle having white lines and the letters ""Z. LL. B."" at the three angles of the triangle, and also wore a green ribbon with a medal with the letter ("ka") in Baybayin script above a depiction of a crossed sword and flag. The password was "Gom-Bur-Za", taken from the names of the three martyrs Mariano Gomez, Jose Burgos and Jacinto Zamora. "Bayani" (Hero) wore a red mask and a sash with green borders, symbolizing courage and hope. The front of the mask had white borders that formed a triangle with three "K"s arranged as if occupying the angles of a triangle within a triangle, and with the letters ""Z. Ll. B."" below. Another password was "Rizal". Countersigns enabled members to recognize one another on the street. A member meeting another member placed the palm of his right hand on his breast and, as he passed the other member, he closed the hands to bring the right index finger and thumb together.
