Editing Warhammer 40,000/9th Edition Tactics/Weapons (section)

====Space Marines====
The Emperor's Space Marines are a jack of all trades army, since they have BY FAR the biggest amount of unit choice in the game. Seriously, you could add together the units from the three smallest armies in the game and marines would still have more stuff altogether. As such, variety is the name of the game with them. However, their standard units will be the regular/primaris marines, T4 S3+ W2. They are the outliner for the MEQ stats, and as such, every army will have dozens of ways to prepare against them in one way or another, and the same for the marine terminators and the TEQs (T5 S2+/5++ W3). They can always use cheaper and weaker units by using scouts (less viable in 9th since [[wat|they are Elites for some reason]]), servitors ('''hah!''') or allying with other imperial factions. Thus, you won't have to deal with hordes against them, though their regular infantry is strong enough to get entire lists made out of them and still pose a threat. Plasma weaponry is usually recommended against them, alongside anything that makes D2 damage. 

In the offensive, their standard weapons are mostly bolter based, with either the bolter (Rapid Fire 1, S4 AP0 D1) or the bolt rifle (Rapid Fire 1, S4 AP-1 D1) being the most common out there. Outside of that, fuck, they have access to so much. Just look at their [[Warhammer_40,000/Tactics/Space_Marines_(9E)|tactics]] page for that.

It's also important to take into account the SM's variety doesn't just come from their units, but also from the amount of chapters and their abilities, some with their own codexes and unique units. Some of the most frequently used chapters are:

*'''Ultramarines:''' The boys in blue are the posterboys of the faction, and are the essential jack of all trades on an army that's already a jack of all trades. They might not excel at any given strategy, but they can adapt to virtually any given situation so countering them outright is easier said than done. Also they can use Guilliman, so take into account all the buffs the Primarch gives them.
*'''Blood Angels:''' The sons of Sanguinius, they are one of the most powerful melee armies in the game as of right now. Expect to suffer charges with melee-centric marine units like vanguard veterans, assault intercessors and their fucking dreadnoughts. You counter them by either shooting at them from afar (something very difficult now that secondary objectives are so important) or by having tough as nails units that survive and fight back.
*'''Space Wolves:''' They are also a melee centric faction, similar to the above, but with a couple of exclusive units to worry about.
*'''Dark Angels:''' They have very scary gunlines since they have a lot of bonuses while static, not to mention a lot of cool option with terminators and bikes.
*'''White Scars:''' Use and abuse of bikers and fast moving units like vanguard veterans. They will have a lot of mobility and will take ground fast.
*'''Deathwatch:''' ''La crème de la crème'' from the Adeptus Astartes, chosen from all chapters to fight the aliens. Highly customizable veterans and kill team formation means they will have a lot of strength and defense (storm shield spam is frequent), thus will make for very tough infantry that can be combined with terminators and other units to create special effects. This comes at the cost of being slightly more expensive than regular marines.
*'''Grey Knights:''' Daemon killers extraordinaire, they are specialized in the fight against Chaos. Also, most of their units are psykers in one way or another, so they'll have a lot of buffs and access to easy mortal wounds. Storm Bolters and multi-damage Power Weapons are very common. Great against smaller, more elite armies, but very weak against hordes that can easily take mortal wounds and keep going.
