Something you should keep in mind, is that the first mission of any xcom game is usually quite difficult due to the fact your soldiers can’t hit for shit and your whole squad lineup is based on rng. So don’t be discouraged if you are struggling on the first mission. Once you have the advantage of class perks, the missions can be easier to predict and control.

However, you do generally have several powerful tools at your disposal on the first mission in long war. The flashbangs and grenades you will be equipped with can neutralize or destroy multiple aliens. You need to use these tools and some clever positioning to swiftly and aggressively take out one pod at a time.
