How many steps does the first rank take during open ranks?

During open ranks, the first rank is required to take two steps forward to create space effectively between the ranks. This movement is crucial for achieving the proper formation and spacing needed for various drill commands and ensuring that all ranks can align properly. By taking two steps forward, the first rank allows the subsequent ranks to have a clear line of sight and ensures that formations are visually and structurally sound. This practice is essential in military drill and ceremony to maintain organization and precision. The other options do not accurately reflect the standard movement required in open ranks.
