Throughout SSG Dime wears an Expert Infantryman's badge (EIB) except in the limo where he has a Combat Infantryman's badge (CIB).
At the hotel, SSG Dime only has six ribbons on his uniform. At the funeral scene, which took place before chronologically, he has eight.
In the movie, the soldiers wear desert uniforms during the show. In the real 2004 NFL Halftime show, the army soldiers wore woodland camouflage uniforms.
Throughout the movie the members of Bravo are seen wearing the patch of the 1st Infantry Division on both shoulders of their uniforms. By tradition the insignia on the right shoulder would be unit a soldier previously served with in combat (Sergeant Shroom has the 101st's on his). Since this is the first combat tour for most of the squad there wouldn't be anything on them. **However, in Iraq it was traditional for units to award FWTS-SSIs ("combat patches") to troops after 30 days in theater, so this is not necessarily an error.
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.

An advertisement for the PrivateFly company can be seen, when that company was created in 2007.
