Equipment and vehicles of the Imperium (Warhammer 40,000)

Space Marine Weapons and Equipment
As the elite fighting arm of the Imperium, Space Marines are equipped with some of the best weapons the Imperium has.

Boltguns
The standard weapon of the Space Marines is the boltgun, also known as a bolter. A bolter is a heavy gun that fires rocket-propelled rounds with mass-reactive explosive payloads. Bolters are made in both pistol and rifle form, as well as the machinegun-like heavy bolter. Terminator Armor is often equipped with a double-barrelled storm bolter.

Assault Cannons
Assault cannons are the miniguns of Warhammer 40K, they are more powerful than the Heavy Bolters.

Flamers
Flamers are basically Flame Throwers that shoot napalm. They come in three forms; one-handed, two-handed and Heavy-Flamers.

Lascannons
Unlike the Imperial Guard, the Space Marines don't make as much use of laser weapons. The major exception to that rule is the Lascannon, a heavy laser weapon capable of blowing holes in tanks with a single shot.

Plasma Weapons
The Space Marines make good use of the tempermental plasma weapons, in pistol and rifle form. Heavy plasma cannons are also widely used, particularly by the Dark Angels chapter. The Imperium's plasma weapons have poor cooling, and thus build up dangerous levels of heat with continuous operation.

Rocket Launchers
Rocket have a capacity to fire two types of missiles, krack and frag. Krack is a simple rocket that can take out a single unit while frag uses a template and can thus take out multiple units.

Power Armor
Possibly the most prominent feature of the Space Marines is their armor, a heavy suit of powered armor that enhances a Space Marine's already superhuman strength, as well as allows them to easily withstand fire than could kill a normal human.

Terminator Armor
Tactical Dreadnought ("Terminator") Armor was originally developed for boarding missions, and sports heavy forward armor. The First Company of each Space Marine Chapter uses Terminator armor extensively, and only those Marines who earn the crux terminatus are permitted to wear it.

Dreadnoughts
Valiant Marines who fall, but do not die, in battle are often interred in Dreadnought Armor, a twenty-foot-tall walking tank, equipped with life-support systems to maintain the Marine indefinitely (at least one Dreadnought's occupant fell during the Horus Heresy and still lives in the 41st millennium) and an array of weapons. Like Terminator Armour, the Dreadnought is heavily-defended against frontal assaults.

Rhino
A fast troop transport, a Rhino can hold up to ten Marines in cramped conditions. The Rhino generally mounts a single storm bolter and is lightly armored. The chasis of the Rhino is very durable, and serves as the basis for other Space Marine vehicles.

Razorback
A Razorback is a variant of the Rhino that sacrifices troop capacity for firepower. Razorbacks are typically armed with twin-linked Heavy Bolters or Lascannons, and are excellent for adding firepower to smaller squads.

Predator
The Predator is heavily-armored variant that, rather than act as a transport, is instead a light tank. Armed with either an Autocannon or twin-linked Lascannon. It can also have Heavy Bolters or Lascannons mounted on side mountings.

Whirlwind
Being a mobile force, the Space Marines have little need for artillery. However, when it is called for, they can utilize the Whirlwind, which is armed with a long-range missile launcher, and can bombard enemy positions in preparation for attack.

Vindicator
When attacking fortified positions, Space Marines use the Vindicator, which fills nearly the entire chassis with the massive, snub-nosed Demolisher Cannon, capable of blasting through the thickest walls. This weapon has proven so effective that the Iron Warriors Traitor legion makes it a point to scavenge these for their own use whenever possible.

Land Speeder
Incredibly fast, the double-seat Land Speeder ground-effect vehicle is used to attack enemy fortfications and heavy weapons from the air.

Land Raider
The Land Raider is to the Rhino what a Humvee is to a Jeep; equipped with superior armor and weaponry, the Raider can also mount a turret-based heavy weapon and act as heavy support to the Marines it carries into battle.

Land Raider Crusader
The Land Raider Crusader is the identical to the standard Land Raider but is armed with different weapons such as twin-linked assault cannons, and hurricane bolters (basically 9 bolters strapped together on each side).
