Star Wars fan film "Jakku: First Wave": Three Stormtroopers stand by the door of their troop transport, helmets off, and talk about why they joined up in the first place.
The short takes place during the first-wave assault at the Battle of Jakku. Jakku is home to "The Force Awakens" protagonist Rey. You might recall the wreckage of starships scattered around the desert planet in the 2015 movie.
