Just a Rifle

Just A Rifle is a famous poem written by an unknown UNSC soldier during the Human-Covenant War, the author was never found as no one ever took credit for its writing and no physical appearance of the poem itself was even found until it was shared onto waypoint, leading some to speculate that it was written by Anti-UEG parties to even ONI themselves. The poem first appeared sometime around 2546 and slowly began to spread and be retold by other soldiers. The poem goes as follows. 
While the poem originally started in the UNSC ranks, it later found itself on Waypoint when a fellow soldier shared it online during her leave and the poem began to grow in popularity among Innsurectionist forces as well after it began to reach their own. This was the start of its debate among the people. Some saw it as Anti-UNSC propaganda due to how it mentions a soldier being stripped of his humanity while others found it as Pro-UNSC propaganda due to its mentions of insulting the aliens and the ending where it says how they'll still fight to protect Earth and her colonies. This would later evolve into conspiracy theories about ONI starting it for whatever reason to even Innsurectionist double agents using the poem to help turn UNSC soldiers away from the UEG and to instead join them. And to this day its meaning is still left unresolved.
Because the poem has many ways to view it from, it is rather hard to say what the writer was trying to portray to the reader, psychologists who read the poem believes that the writer at the time would have most likely been struggling to come to terms about their part in the war and the actions they partook in seeing it as a way to help with their inner struggle and thoughts while also trying to remind themselves of why they were there. This is the most accepted theory of it's meaning.
