btw the song is done in the first person form of the air force chaplain giving his blessings to the pilots.

"First person" means 'from the standpoint of', using pronouns like 'I', and 'me'. This is in the third person, using words like 'he' and 'him'. But then again, this site is not about grammar lessons. So thanks anyway.

Also, there are indeed no bayonnets in the air force, and men don't stand in line before battle in the air force. They're soldiers, which is why he refers to them repeatedly as such.

An error occured.
