We would say the rhetorical context of the ad is getting people, specifically, men to join the army. The photo used in the ad is what seems to be a man jumping over the space between two rocks holding a gun, and screaming. It makes it look like he’s really taking action, which is the first thought that usually comes to mind when you think about the army. The message that follows at the bottom of the ad is basically a manipulative persuasive saying that to better yourself, you need to join the army. 

What was life like in this year? 

This ad was published after the end of the Persian Gulf War and during the Bosnia intervention, where the U.S had to deploy American forces to establish peace in Bosnia and Yugoslavia. This was when enlisting in the military now became voluntary rather than compulsory. Humanitarian and peacekeeping activities also surged around the same time. 

What do we need to know about this time period that will help us to better understand the speaker, subject, audience, purpose, context, and kairos of the ad?

We would need to know the events that were happening when the ad was published, particularly the events that involve politics and the military. It is important to have some knowledge of conflicts that are going on around the world in order to understand the purpose of the ad is, and what the army is aiming for, and who they are targeting.
