After checking the FAQ and finding no entry, I went back to the book.
Inspiration (Level 1-5)
Some Officers or Individuals project such an aura of authority, intimidation, or are so respected in the eys of their peers/underlings, that they can motivate others and enforce Morale during times of distress and panic. Leaders with this ability may add their level of Inspiration to the effective LD value for both themselves and friendly models within their command radius.
By my understanding of the rule and the fluff, it seems as if this may be used for any LD test where the above criteria are met. After all, it does state, "...motivate others and enforce Morale..." Motivating others can clearly be read to mean that the ability may be used to add to effective LD for things such as Wait, Dive for Cover, Dire, Panic, Rally, et al.
It could, even, be argued that it could be used for Initiative. I will get back to you on that one.
