I will be at the rifle range in Edmonton, unfortunately.
If looking for other military themed attractions in Calgary, you can also try:
Battalion Park

Peacekeeper Park

The latter two have the virtue of being free and without restricted access. Battalion Park has some good interpretive boards and a fine view of the mountains as well as the old Camp Sarcee.
Mewata Armouries
http://en.wikipedia.org/wiki/Mewata_Armoury
Visit the Sherman, Bailey Bridge and Universal Carrier out front - walk right up. Another one of our many M4A2E8 (?) gate guards. Not a whole lot to see inside the armouries, and may be closed if there are no units training on the weekend, but there are a few historic photos on the walls inside.
Central Memorial Park

Where the civic cenotaph is, plus two war memorials (one to the South African War and another to the First World War, on the opposite end of the park from the cenotaph, outside the public library).
