Warhammer 40,000/Tactics/Space Marines(9E)

Why Play Space Marines

Pros

• 9th seems to be shafting hordes and infantry - This means your elite dudes can hammer down on lesser units easier than before.
• Dreadnoughts can stomp around the battlefield blasting the big guns!
• A lot of different units.
• Seems everybody got upgraded machine spirits, Astartes vehicles are better than ever, though more expensive.
• Easy for beginners to play, yet rewarding for experts. Can be customized to focus on many specific elements (e.g. Terminators, mass jump pack assaults, etc.) with varying grades of viability.
• Units can do something of everything, with an answer to every situation.
• A common trend with Imperial armies, your Troop choices aren't tax, being actually good.
• You're GW's favorites, so you'll always be the first to get anything new.
• Loads of powerful characters to choose from, many of which have potent buffs to surrounding units.
• You'll almost always have an armour save.
• Many of your models are simple to paint with their solid colors and easily identified highlight areas---This makes painting your army very beginner friendly.
• Now packing bigger and better weapons infantry weapons than other Imperial armies.
• Primaris flushed out more with assault variants.

Cons

• 9th Edition seems to favor reducing the size of armies for quicker battles. This results in increased points costs for Marines while magnifying issues with being outnumbered.
• Other choppy armies can still swing with the best any day, do be careful.
• Troops section is getting genuinely complicated.
• Overwatch gimmicks are largely null and void, with only a few exceptions.
• So many different units that it can be difficult to determine which ones are best in a given situation.
• As the most popular army by a long shot, most people build their armies with at least a few options for killing Space Marines present.
• All the characters that used to be part of other units (e.g. Apothecary, Champion) moved to the Elites slot, which was already rather crowded. *Consider bringing in an extra Vanguard detachment or two.
• You will almost always be outnumbered and will struggle at times to claim objectives, though some Chapter tactics make use of low model counts.
• Being the "alpha army" for so long tends to reap powerful counters elsewhere.
• Primaris are still beefy and expensive and can still get swamped in cheap, high volume, low AP hits
