Regarding to Wikipedia "Nenonen developed the Finnish Army's artillery and tactics that proved decisive in the defensive victory in the Battle of Tali-Ihantala. The trajectory calculation formulas he developed are still in use today by all modern artillery" Wikipedia Could someone help me to explain this a bit further, what made his development of the Finnish artillery so good and how did it work? Do you have any books to recommend about this, either in Swedish or in English? Thanks for your time and help! Paul
