First Person Shooter games typically use the same style characteristics, narrative structured and representation.
The representation of the class menus in most first person shooters games are similar like this where you start a match with the option of picking 1 of your many classes to play with. These classes usually consist of primary weapons, sidearms and equipment. Like you'd expect games like originality and with this game Call of Duty they have included Perks which give you extra ability's and wild cards which let you extend load outs. To help you find the best setup.

The Battlefield representation of the class menu is much smaller and more condense this is to show more of the map you will be playing on and what is happening on the map and what your team mates are doing. They do this because they want to be a little different and show the player a preview of what is to come. Being smaller the screen looks much cleaner and gives the menu a better appearance.
Rainbow Six Siege Gameplay
Rainbow Six Siege shows that there can be different types of first person shooters as this is a slow paced first person shooter compared to Call of Dutys quick paced gameplay this is because Rainbow Six Siege is a very technical game and makes the person be more careful and communicate with there team mates unlike Call of Duty or Halo. Although it still has similar traits to the other games this shows that it can not still get away from the main stream first person shooter.
