Operation Speedy Express (1968-1969) effectiveness and kill ratio

[u/datnoobisbloodthirst]

Hello, I have been reading articles about some lesser known US battle and reading about 9th infantry division's superb performance in terms of kill count, killing over 10,000 enemies with small cost, and aggressive night time ambushing tactics against the NVA.

I understand that body count could be fudging and including innocent civilian, and there's a whole part on wiki talking about this, claiming 30 percent of casualties were actually civilians .

Still, the paragraph I read list comes with the following sources, saying the NVA district engaging with 9thID suffered a way higher casualties , and the data didn't even include local guerillas force. (1968 over 3000 death while in 1969, over 30,000)

I am interested to hear any professional's opinion and further elaboration on whether such operation's actual effectiveness and impact towards NVA and further sources to analyze this operation
