HS friend of mine was SF so this info is OEF/OIF-era information and could very likely be different today. You are not going to be able to just pick whatever weapon you want, but you are going to have a wide array of training and be able to pick something more specialized to the mission, whereas for the most part if you're some random infantry grunt you just use your rifle for everything. But if you're a random infantry grunt your M4 is going to be a good rifle for all your missions - you're not going to need a silenced SMG/PCC or something that can reach out 800 yards. Sidearms are similar, it's not carte blanche but among what is available you can carry whatever you are comfortable with within the scope of the mission.
You're much more likely to see SF guys with short-barreled rifles, pistol-caliber carbines, suppressors on everything, etc. For all the (justified) complaints about military overspending, there just aren't the resources or training available to give every rifleman a suppressor.
