Setting: There isn't really a main setting judging by the trailer as they always seem to be in different locations.
Props: There are many different types of weapons seen in the clip ranging from big machine guns to pistols. With many explosions you can tell that these will be used frequently.
Costumes: All the main characters are normally wearing the army suits but they do change when they are going out for the evening.
Sounds: There is both digetic and non digetic through out the trailer. There is fast paced music in the background and there is also explosions and gun shots in which the characters can hear as well.
Representation: You can tell by watching just 2 minutes of the film that the characters all get along very well as there are always joking with each other and they all come across very strong.
There are a few natural themes but the main one is seeing a giant building being blown up in the background.
