Editing Warhammer 40,000/7th Edition Tactics/Adeptus Custodes (section)

===Troops===
*'''Custodian Guard Squad''': Custodes all have Terminator-grade saves and combined with being able to Look Out Sir! on each other thanks to being Characters, as well as having the Fearless rule means they can be the meatshield squad of your dreams, easily able to rival infamous ones like Lychguard. While ultimately quite expensive they are highly survivable in either weapon loadout and can match the damage output of just about any other close combat squad. Much like their fluff implies, while individually being amazing fighters they lack the tactical flexibility of their brothers the Astartes, with shortcomings in serious long-range firepower, effective anti-armour (let your other units worry about that, its beneath these guys anyway), and mobility (unless you deep strike or buy a Land Raider). Don't use them as end-all units, instead treat them as what they are, a powerful assault combat squad that can hold their own in a fight. May take a Venerable Land Raider as a DT, which is something you should likely have at least one of if you're running a pure Custodes force since your Anti-Armour's rather limited without it.
**Something worth considering is getting more Custodes for one unit, rather than multiple units of Custodes to take advantage of the '''Block''' rule.  In general the more Custodes with spears that are a part of the unit, the more attacks you can Block safely which can really help you out if you're up against a melee powerhouse.  There's no harm in attempting to block either and as a quick example, if 6 Custodes have spears, you can ignore 3 attacks on average, no matter who they're from.  You can even use the Block rule to keep somebody alive in a challenge since the Custodes can (albeit unfairly) block the enemy challenger's blows (although it is fitting for a squad of bodyguards).  Quite ironically for a group that's always made out to fight as individuals, they've better close combat teamwork than most Marines.
