I always think the Project would probably copy a lot of SADF equipment from the 70s and 80s, when not going hitech. Cheap easily, produced, durable and able to get dragged for 100s of kilometers by truck around rough ground.
Probably the Valkiri would be a great sucker punch weapon. Find a big encampment of bandits, then with one blow send them scuttling away. A blow that could be loaded on the back of a very ordinary medium truck.
