Gunner, beat me to most of it...
Hmm... sounds like you're from Ottawa ;D
Impact statment... I'm sure I'm not the only one wondering, but what would the statement be pertaining to? Impact on your unit, should they lose you to a deployment for an extended period of time, or impact on your family with you being gone for an extended period of time?
Not that it has a lot of bearing, but are you reg or reserve? What is your rank level?
I have heard of people being requested to submit memo's substantiating their request for deployment, but I have never heard of units requesting an Impact Statement. (nobody who I am deploying with has mentionned anything about such a statement)
