Little Mix - Salute Lyrics Meaning

It's obviously not about an actual war as others suggest. It is was about a call to a literal battlefield, it wouldn't say "Don't need ammunition" "We don't need no camouflage" - unless they are suggesting women are daft enough to go into battlefield unprepared, with no plan except to "hit you with the truth". It's about asserting women's rights where they are - whatever country they are in.
