There's no such thing as the best weapon. You can only define the best weapon for a already given situation.
The best weapon is the one that allow you to utilize your army as a whole.
But one weapon is never enough.
Answer: It depends on how you use them. They are not to good at range, but when you get within 24 inches with a few boltguns they're amazing. Their tanks are pretty good but they don't have a substantial long range blast template weapon. Their fast attack is some of the best in my view, transports are really good for transports. Overall if you're looking for a short range good heavy support, and good close combat, Space Marines are your best bet.Another answer: In short no, the space marines are not the best. Each army has both its strengths and weaknesses. Space marines are powerful and one of the most popular armies, but they are small in numbers. Check out each army's strengths and weaknesses. Check them all out, find out which one YOU like best, if you like necrons go with them, tau go with them. Do what YOU want. In short again, space marines are not necessarily THE best.
The overall best weapon is the Plasma Cutter. This is the first weapon you will acquire in the game.
The best thing to do is buy the codex
No. In the marines, like any other branch of military service, you are assigned a weapon and given ammunition for that particular weapon. You learn to use that weapon. If a marine is fighting in a battle, he can find another weapon and start using it.
space marines cool because they hot before now they cool.
It depends where you are in situation: Melee Space Wolves Range Space Marines Psychic Space Wolves (only just) Vs. Vehicles/Light Infantry Space Marines Vs. Heavy Infantry Space Wolves Look Unpainted Space Wolves Paint Scheme Look Space Marines All-Round Space Wolves (I Reckon)
NO, Valkries are for the Imperial guard. Space Marines use Thunderhawk Gunships.
Army and Marines.
It depends on the person who is playing, but Space Marines are considered to be the best all-rounders.
Space Marines carry a variety of weapons based on individual chapters and what each Marine (or the squad he's apart of) is meant to do. Devastators carry heavy weapons such as las cannons and plasma cannons among others. Assault Marines are meant to get into close combat, so they carry pistols and close combat weapons like chain swords and power weapons. A standard tactical marine would carry a standard issue bolter, and they all would carry a combat knife & grenades.
