Answer
Tau. These guys will shoot you to bits.
The Tau Empire are the best shooters in 40k, Necrons can also field some pretty devastating fire, while Imperial Guard tanks dominate all before them.
Answer
Tyranids, definitely.
If you are serious about Warhammer 40K you can only play Orks.
Defineitley 40K.
In warhammer terms TAU is a young yet sophisticated army which includes kroots and fire units. Personally I believe Tau are the best with Eldar in warhammer 40k.
Anything that is close combat oriented & can move up the table quickly.

No they do not, only one needs to be in range.
it is a warhammer 40k peice for the eldar army there fast atack and conciderd the best way to take down a necron monilith!
No, but it always looks a lot better if your army is matching, and your opponent with appreciate it.
There is no best and/or worst army in Warhammer 40k. The points system is mostly fair and reflects how these armies should be played. Tau are good at shooting but not so much at close combat, same with Orks and Tyranids, they're not the best at shooting but can eat you up at close combat (most Orks have a BS of 2 I think)
Answer Warhammer Epic is much smaller than 40K. It is also cheaper.
Games Workshop made the Warhammer 40k Tabletop Game.
A summary of the blind rule in Warhammer 40K is when shooting USR, the target will take an initiative test, if the target fails the test then the WS & BS are set to 1 until the end of their next turn.
