Editing Warhammer 40,000/8th Edition Tactics (section)

==Required Reading==
Since you need a goddamn flow chart to figure out which books are needed to play the game anymore, here is a basic primer for new players. You are going to need the following in this order: 
*A copy of the Core Rulebook. That flyer you picked up at a test event or printed off online may have the base rules for the game, but the Core Rulebook will include details on everything else, including mission types, terrain, and stratagem use. So do yourself a favor and grab it.
*A copy of your army's codex. This will have the majority of what you need to play said army, including unit entries, warlord traits, relics, stratagems, and point costs. Our own tactics pages contain some of that information, but for legal reasons we can't give full statlines and points costs for the units. ([http://wahapedia.ru/wh40k8ed/the-rules/playing-this-game/ Certain Russians], however, don't care so much about petty things like 'laws'.) If your army is one of those unlucky ones that has not gotten a codex yet, you should obtain the relevant index containing their information. As 8th edition ages, the indexes are essentially obsolete; the legacy units and options not carried over to the codexes have their rules available for free on GW's website, under the "Warhammer Legends" section. 
*Your army's online errata and FAQ printed off the main Games Workshop website. A version comes out shortly after each codex, and the game designers are not afraid to completely rewrite a unit's rules if they realize they fucked something up. GW also schedules a "Big FAQ" to come out twice a year to address balance issues as they come up and make wider, more sweeping changes they want to get feedback for before they're officially added to the core rules.  
*The most recent Chapter Approved (maybe). A grab bag of new rules, updates, and experimental shit. If your army codex came out in 2017, some of your units already have point costs changes contained within. If you have not received a codex yet, you can find a small consolation prize until they get around to you. If your army received a codex in 2018, skip it unless your group prefers the alternate mission options. 
*Your army's copy of the Psychic Awakening. It will have some new strategems, updated rules, and potentially new models.

Other Reading
*The Forge World Indexes, if you don't mind selling a kidney for resin. These are currently out of print due to a planned replacement with updated rules. 
*Warhammer Legends on the community website, which include rules for units GW no longer sells. Legends units will still be allowed in both matched play and narrative play, but GW discourages competitive tournaments from allowing them due to them not receiving future balance updates. Warhammer Legends has effectively made the non-FW indexes that came out at the start of the edition unnecessary.
