in the car with three other “comrades”....since when do we refer to friends by that word...
I think it is poor editing. The writer meant the soldier was killed with three comrades. I had the same first impression, and had to re-read it.
They might frown on that, but that is how I would have written it.
It is like a t-shirt I saw recently:
"Let's eat, Grandma"
"Let's eat Grandma"
COMMAS SAVE LIVES!
