Modern Warfare 2: Actions Allowed

As opposed to normal actions, which we can perform in reality, I am assuming actions allowed are actions not easily performed in reality. The first action allowed that I noticed was being able to switch guns with ease. Players apparently carry multiple guns around with them at the same time and can switch them at any time even though in reality this may become a cumbersome task because of how heavy carrying multiple guns would be. One player even seemed to be carrying around a rocket launcher in his arsenal which is completely unrealistic.

The other major action allowed is being able to be revived when dead or close to being dead. We see this in many video games where players are able to attain health packs in order to avoid dying or being able to respawn.

Modern Warefare 2, along with most other first person shooter games, provides a radar for its players so that they can see where they are inside of a "level." It is unlikely that players in a real battlefield will have radar communicating to them where they are and exactly where everyone else is.

I also noted the following actions allowed but after reconsideration, they appear to be more along the lines of normal actions so I will not go into detail: use scope, fight without a gun, stab someone, reload guns quickly.
