In a Corps (Regiments with more than one Battalion), equalized Battalions are still called Battalions, equalized Squadrons are called Grand Divisions, equalized Companies or Troops are called Divisions, equalized Platoons are called Subdivisions, equalized Sections are still called Sections, and equalized Squads or Brigades are called Subsections. Squadrons were originally units of 6 infantry platoons during the pike and shot era, with 4 pike platoons in the middle and two shot platoon on the side, then a shift to two pike platoons in the middle and four shot platoon at the side, and finally 6 shot platoons with bayonets. The term Squadron comes from the square shape the Tercio makes with the pikes as a Spanish Square. Brigades are used by the French speaking countries to distinguish Squad from Squadron for unit types where Squadron is applicable.
