Issues with hard difficulty in skirmish mode

[jorxe33]

let me tell you that I've played the game in heroic level and it was easy for me. You only have to atack the enemy tanks by the flanks, accumulate points and little by little buy tanks and rangers or sas, then when you have a good army, atack simultaneously all the "checkpoints" or "flags" like an avalanche. You win easy ¡in the heroic level!
