Hi everyone, i decided to install the expansion pack last week and play it in veteran difficulty. At the first times i played very smoothly and completed 5 missions very easily but after the tank missions come, i couldn't continue because of the extreme difficulty. For example in the sixth mission which is "First Strike", i played at least 20 times to complete this mission. After i complete that mission i feel relaxed but the next missions is harder than that one. I cannot deal with 15 tanks with my 2 tanks. Any suggestions??
