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

===Melee Weapons===

*'''Heavy Thunder Hammer:''' An enormous two-handed Thunder Hammer built for smashing in Xenos heads, this 18 point melee weapon hits at a staggering SX2, AP-3, D6(!) Damage. Further, Wound rolls of 6 automatically cause 6 Damage. It has the same -1 to-hit penalty of a regular Thunder Hammer, so make sure you've got a source of re-rolls to make every swing count (cause hitting 50% of the time ins't good enough). Taking a melee weapon that costs more than the marine who's carrying it isn't always a great choice, but multiple lascannon-strength melee attacks boosted by Mission Tactics can lay low even the biggest of xeno monsters (or enemy vehicles and characters). Be wary of overkill and choose your targets wisely - if you're killing enemies with 3 wounds or less, the regular Thunder Hammer is cheaper at 16 points and does a consistent 3 Damage, but if you fancy ghetto stomping a carnifex, here is your weapon of choice. Notably, the Heavy Thunder Hammer replaces both weapons and can only be taken by standard Deathwatch Veterans and Vanguard Veterans. 
**With a Doctrine Stratagem active, the damage boost occurs on a 5+ due to adding 1 to the wound rolls.
*'''Guardian Spear:''' Only available to the Watchmaster, this Custodes weapon is essentially a Master-Crafted Bolter combined with a Relic Blade. S+1, AP-3, D3 Damage provides a nice balance between S, AP, and damage for good mileage against most targets. 
*'''Xenophase Blade:''' Literally jacking Necron Phase Swords, it's a Power Sword that forces successful invuln saves to be re-rolled. A 1-point upgrade over the standard power sword, it's not a bad choice at all, particularly when facing enemies who fall back on invuln saves against your AP -3 blade. Vet Sergeants and Watch Captains can take this.
*'''Power Weapons:''' Sword is S user AP-3, Axe is S user+1 AP-2 and Maul is S user+2 AP-1. None give extra attacks. Bear in mind that Doctrine stratagem can give +1 to wound and mission tactics gives reroll ones to wound, but we don't have bonus to AP. As such the sword should be preferred in almost all cases where you need a one handed melee weapon.
**'''Power Sword:'''
**'''Power Axe:'''
**'''Power Maul:'''
**'''Power Fist:'''
*'''Thunder Hammer:''' Regular thunder hammer. Compared to the heavy version, it trades one handedness for a fixed damage of 3. Perfectly reasonable against things with 3 or less wounds, especially as it allows you to also grab a combi-something to go with it.
*'''Chainsword:''' Free, but does give +1A at Suser AP0. Reasonable backup for a shooty unit rather than something to give a melee unit.
*'''Lightning Claw:''' Rerolling wounds overlaps with mission tactics, so don't use against your current mission tactics target. Doctrine helps though, going from rerollable 4+ (75%) to rerollable 3+ (88.8%) against many targets, but thunder hammers may need that buff more. Hitting things with T8+ is suboptimal but you'll still get 30.5% wound rate, so can do something in a pinch.  Benefits greatly from reroll to hit, e.g. pair with a captain, chaplain,  or watch master. Bog standard vets have access to these, so you can get 32 attacks with reroll to wound and -2AP out of a troops slot, perfect for murdering hordes.
