My apologies if this question was already answered. I am new to Arma 3. I bought the main game with the DLC Jet (pre-order) last month. Just today, the DLC jet was installed on my Steam account. However, I cannot locate the DLC on my game or know where to find it to play the DLC jet. I appreciated if anyone can show me the method and the "how to..." process in playing the DLC? Thanks all...
