Defend skill, how to detect it?

[Kike]

Hello everybody! Today I was trying to make a hero skill based on Footman's Defend, it should basically has two effects, reduce magic damage received and increses the Footman's armor, all the effects should only happen if the Hero is with Defend active, so, if he deactivates it, he losses his bonus. The magical damage reduction is easy to do, but I don't know how to add and remove armor becouse I don't know how to detect if Defend is on or off! Any clues about that?

Event - A unit issued an order with no target
Condition - (Issued order) Equal to defend
Actions....

Something like the above. To detect the defend turned off, change the 'defend' string to 'undefend'.
