Exactly. WW2 is full of great examples because even the most curb-stomping victories and defeats tended to average out to 5:1 casualty ratios or less.
The Stalingrad offensive is a personal favorite since it was around 3:1 in the first half and 1:3 after operation Uranus
(despite both sides claiming 10:1 or more at various stages of the offensive)
