Who, What, When, Where

We have photos of a gunner from several points in his career. Possibly you can help identify the who, what, when, where!

A visit from the Army Commander? I've thrown in an additional photo of the gentleman being led in by the sentry who stopped him at the edge of the position. Who's the number 1? What was the name of the exercise? When was it? and Where did it take place?

Same gunner is in this photo. But it doesn't look like he's the number 1! Who is the number 1? What was the name of the exercise? When was it? and Where did it take place? What's with the high ranking number 2?

Again we have the same photogenic gunner. But this time he's got one hook! A qualified Gunner! That's Major Bob Foulis leading the service in the North Fort Lewis. I can recognize WO? Brian Harmon, Bdr Shane Culver, Gnr Colin Parkinson and MWO Bill Amos. Recognize anyone else? When did this take place? 

Appear to be Gunner Parkinson in this photo as well. Chilliwack exercise including grenades? The first two appear to go together. Is the third photo from the same ex?
