Prompted by recent remembrance day celebrations, it seems to me that the term PoWs is inconsistent with pluralization conventions.
Runs Batted In --> RBI
Prisoners of War--> PoW (shouldn't this be the plural?)
I read that laser appears to have become a noun unto itself and is thus pluralized as lasers.
Is PoWs an accepted noun or is it an oddly pluralized acronym?
Other acronym pluralization questions that don't address PoW(s) directly:
What is the correct way to define an acronym when its first appearance is plural?
Should acronyms that are actually hidden plurals be treated as plural?
