And the CA1928 105mm semi-automatic artillery piece was actually developed collaboratively between Australasia and Germany as its predecessor, the GA1906 model.
This was a large-caliber semi-automatic artillery piece modeled after the M1897 cannon and was, overall, quite successful.
But after all, it was a product from over twenty years ago, so the CA1928 105mm semi-automatic artillery was essentially a new product improved by the Royal Military Factory.
If nothing unexpected happens, the next large-scale war should see the Australasia Army extensively equipped with CA1928 105mm semi-automatic artillery, M1928 150mm howitzers, M1922 75mm semi-automatic artillery, and CA-2 27mm anti-aircraft guns.
The first three types of artillery are meant to suppress enemy forces with firepower, while the anti-aircraft guns are specifically designed to combat enemy airplanes.
