“If a soldier shoots at a mark in the trench, firecrackers detonate next to him, a tank drives in the back and combat ammunition is fired at a metre above his head so that he gets utilized to wheezing bullets... this is truly realistic training” - says Gen. Jarosław Groadziński, Counselor Coordinator of the Chief of General Staff of the WP about training Ukrainian soldiers, whom he dealt with as deputy commander of safety Assistance Group - Ukraine (SAG-U). As he emphasizes, experience from this activity should be implemented in Poland as shortly as possible, primarily concerning the change of reasoning about reserves. — “We should think about creating a Reserve Corps. It would be trained, ready-made sub-troops that train together. The same people meet. These are ready-made operational modules.”
