US Army squads are not designated with letters, they are numbered based on their respective platoon and company's table of organization (so many squads to a platoon, so many platoons to a company, companies to a battalion, battalions to a brigade, brigades to a division). Platoons are numbered in the same manner, respective to their company. A company may be designated with a letter (in the cases of companies that do not deploy except as part of their parent battalion) or with a number (in the cases of "modular" companies that may deploy separately from their parent battalion and placed under the control of a "modular" battalion headquarters when they arrive in theater). Billy's squad would be correctly designated as the 2nd Squad, (numbered) Platoon, (lettered) Company, (numbered) Battalion, (numbered) Brigade of the (numbered) Division. Since this designation is fairly complicated for non-military personnel, Billy and his squad mates would most likely be recognized as Soldiers from the same Division (since they would all wear that Division's patch), without mention of their specific unit within the Division.The reasoning for Billy's squad being called "Bravo Squad" is explained in the book as being a result of incorrect reporting when the video footage of their battle was aired on the news.
