So i bought the book for cod5 and as a read stuff about the multiplayer stuff i will post some of the nice tips for you guys who decided not to buy the book or wasnt able for whatever reason you had.
Tip # 1) Tanks can be killed by a satchel charge (aka:c4) if it is throw on the ground and the tank runs over it and you blow it up. so in essence if you can get it under the tank your golden and the tank and screwed.
Hint) Black Dogs=enemy Brown and White Dogs=Friendly
