2) If you are purchasing your own equipment, are you required to purchase specific items, or is it a matter of personal preference (in your weapons; dive gear, etc)? Again in SOF you can do just about anything you want to as long as it works, which makes it conform to a certain range. No personal firearms are allowed and no "exotic" blades--i.e. battle axes or fantasy swords. Stuff like dive gear is pretty wide open
3) Is there a difference in what is provided to enlisted vs. officers; spec ops vs. regular troops? No real difference between O and E except job specific stuff. Huge differenc between SOF and Regular, even more difference between Regular "combat" Units and regular "support Units" (doesn't seem to matter they are driving on the same streets) and between regular and guard/reserve units---well, least when I was there I felt sorry for the Res/guard folks
