Absolutely, Mr. Harris.
First of all with respect to a coalition campaign, there is a shared joint view of the targets, in this case in Iraq. Those are prioritized against the objectives that may be in play at the time, in coordination with Iraqis.
The tasking of missions, so for Canadian aircraft or any of our allied aircraft, is coordinated through CENTCOM, and targets are assigned against those missions.
Those then come into a Canadian chain of command. We have a theatre engagement authority in the air operation centre that is ultimately in charge of viewing that every target Canada would consider striking is, as a Canadian view, in line with our rules of engagement, which I'll get to.
If there is a risk of collateral damage or another risk in the conduct of that target, it is then pushed out of theatre to General Vance. He can approve a certain level of targets. If he can't approve something, it ultimately goes up to the Chief of the Defence Staff. That targeting chain is completely approved by Canada, and ultimately by the pilot when he releases the weapons.
We don't generally talk about rules of engagement writ large. Suffice it to say the chief approves specific rules of engagement that enable the disciplined use of force by Canadian Forces in this particular conduct.
There is a set of rules of engagement, which I'm not going to discuss right now, but I can tell you from an allied perspective that this is the most accurate conflict we've ever been party to. It's accurate because of the weapons we're using; it's accurate because of the limits we've put on collateral damage, and because we are taking such care, you haven't seen aircraft drop on every strike mission.
With respect to the targets and this specific one, it's clear that as a campaign objective, the flooding of the Euphrates or the denying of water to downstream is of great concern to the Iraqi government. Hence that target would come up and be prioritized within that period of time.
My army colleagues would tell you that engineering equipment is some of the most valuable and it is greatly protected on a battlefield. Hence in this case, it was viewed as a highly prioritized target by CENTCOM and then by the Canadian chain, and it was ultimately approved for a Canadian strike.
