I recall reading a SF short story, probably in an SF anthology from the 60s, 70s, or 80s.
The story was all about a community or society reacting to the invention of a wondrous new military technology, and how it was going to revolutionise their war with a long standing enemy. There might have been conversations about how it couldn't possibly work, or the ramifications of being too successful in war, and so on.
The story was fairly quiet and neutral about the setting, and what exactly this new technology was .. right up to the final page where it was revealed to be the bow and arrow. And the society being a stone age tribe.
