In every mission there is a piece of cheese. Some people might think it does something special. It doesn't.
(You can shoot at it and it won't do a thing except put a bullet hole in it).
So don't waste your time trying to find all the pieces of cheese.
Another thing. If you want to get easy gold medals in the firing range select the laptop (bronze, silver,or gold), switch it to sentry mode and throw it.
While it's in the air pause and exit. Switch to another weapon and if you did it correctly the Laptop will be on the floor shooting at the target(s).
P.S. The Laptop will not affect your accuracy score.
