Tips

Hello, can you give me some tips for me in this game? I have unlocked planes (rebirth 7), but planes of another players very often killing me everytime. I haven´t fulfilled any task from Operations. Another planes using rockets for killing me. My base is big, i have bunker, drone control center, port, tank factory, helipad, runway, hangairs for helicopters and planes. This rebirth 7 I have in 90% progress. Thanks

Sorry for my english, I am Slovak.
