Just posting if someone is trying to find a tank macro.

Copied from another post.. Raid targets if your in a pug....
/script SetRaidTarget("target", n)

where n is:

1 Yellow 4-point Star
2 Orange Circle
3 Purple Diamond
4 Green Triangle
5 White Crescent Moon
6 Blue Square
7 Red "X" Cross
8 White Skull

You can bind that to a key or include it in the below macro if you use a macro length extender addon.

/run SetCVar("Sound_EnableSFX","0")
/use 13
/use 14
/startattack
/castrandom Holy Shield, Hammer of the Righteous, Shield of Righteousness, Judgement of Light, Hammer of Wrath, Exorcism, Consecration
/run SetCVar("Sound_EnableSFX","1")

Change judgement of light to wisdom if you need mana.

I have a second macro for pulling..

#showtooltip Avenger's Shield
/castsequence reset=10 Seal of Corruption, Avenger's shield
