Over 140,000 German soldiers were trained on the base from 1974-2000, under the auspices of the German Army Training Establishment Shilo (GATES). Apparently the terrain in the area is quite similar to that in Germany in the areas where operations would presumably take place in a new European war. Hence the importance of the Base for training our German allies.
Much of CFB Shilo's 40,000 hectare area is devoted to artillery ranges where weapons like the massive 155mm howitzer could be exercised. I can recall as a teenager seeing these M109s being transported on flatbeds to Shilo and I think this is the genesis of my affinity for the model.
Battlefront's M109G certainly looks the business, armed with a massive 155mm gun. My only criticism of the model's design is that I'd like the gun designed to be elevated a bit more. However, the way the part is designed renders it capable of assembly in only one way. Also, I had a miscast on one of the track sections, but it's not that noticeable when assembled.
