countercharge

An accusation against an opponent in an argument in response to the opponent's accusations.

We’ll get to the merits of the charges and countercharges shortly, but first it’s worth considering why, beyond entertainment value, all this matters.

An thrust or charge against an enemy in response to their previous attack.

[…] charges and countercharges, retreats and counterretreats, attackin' and fallin' back.

To reverse the colors; to make counterchanged.
