The story is about "George Orwell's". He want to express his military life, when first time he got rifle in his hand. They were marching, and he was thinking like a normal guy as he just joined the Military, that what if... he does this or this? This expresses the fear, excitement, respect in his heart for his profession, and he loves it.
Hope this helps!
