I am new here. I love the game but there are two single missions I cannot beat on single missions: KorsunPocket Escorting Sturmoviks and Invasion of Sicily Armored Defense. I have read and tried everything on the forum. Best on Armored Defense 12 minutes and some seconds, 16 planes shot down. Best on Escorting Sturmoviks 4 minutes 48 seconds 6 planes shot down. I do not understand what is needed in either mission to complete it. Any help would be greatly appreciated. I may not be the best player, but I have beaten everything else in the game except simulator; I have only completed battle of britain on this setting. My main problem is I do not understand the goals of these two missions; is it how many planes shot down, how long the defended last or exactly what and how do I achieve it? Thanks for any help.
