Fortifications and siege techniques in Cossacks style games needs lot of improvements. Strange wood pales, separate towers, long stone walls easy destroyable with archers fire arrows or grenadiers hand grenades looks foolish. I got some ideas for improvements in future add-ons, modes or DLC. Fortifications in the game could include more defensive structures as like blockhouse, tower, bastion, castle, fort, fortress, fleche, redoubt, scone trench, wall. Fixed fortifications and simple fieldworks are well come. They were commonly used and sieges were characteristic warfare at that period. It would be fine include few types of garrisoned fortifications e.g. Blockhouse = 12 infantrymen Tower = few crewmen needed for 1, 2, 3, cannons Bastion = 24 infantrymen and some artillerymen for 2, 3, 4 cannons Castle = 36 infantrymen and some artillerymen for 3, 4, 5 cannons Fort = 72 infantrymen, 15 cavalrymen and some artillerymen for 4, 5, 6 cannons Fortress = 240 infantrymen, 15 cavalrymen and some artillerymen for 8, 9, 10 cannons Four garrisoned fortifications require officer or General commanders. Bastion, Castle and Fort needs infantry officer, drummer and flag bearer Fortress needs 3 officers, 3 drummers, 3 flag bearers and 1 General with Adjutant Each garrisoned cannon needs 4 artillerymen crew inside fortification. Well supplied, garrisoned and reinforced fortifications could offer stronger defence. Fortification fire power depend on garrisoned units, number of cannons and ammunition. Garrisoned cannon without additional supply can fire only 10 shots, later fortification require supply delivered with horse drawn ammunition caissons and supply wagons. Garrison units could make sorties, capture or destroy enemy cannons, wagons and peasants. Fixed stone fortifications are not destroyable with archers fire arrows, grenadiers hand grenades and light artillery. Enemy garrisoned fortifications could be captured during siege. Besieging force could blockade enemy fortification and use siege techniques as fallows. Heavy artillery bombard defences, partly destroy fortifications and enemy garrison can suffer some losses. Meanwhile sappers or peasants dig scone trenches around fortifications, build fieldworks, virtual tunnel and lay mine under fortification’s wall. Explosion could make breach hole in the wall. Besiegers can offer honourable capitulation or storm enemy fortification through that breach and capture fortification. Then conqueror can repair defences and create own garrison. Well supplied strong garrison can withstand even long sieges and repel weaker attackers. During long sieges poorly supplied garrison as well as blockading forces placed around besieged fortification zone could suffer losses inflicted by starvation and diseases.
