Defense Minister Gallant told a Knesset panel that the IDF has "killed or wounded 60 percent" of Hamas' forces in Gaza, and "dismantled 25 battalions or the vast majority of them."
That is a rate of 6.6 % a month. So killing or wounding the remaining 40% could mean the IDF finishing their task in another 6 months. Another 25,000 Palestinians to be killed, mostly civilians, if the usual rate continues. That is if they are correct about 60% of Hamas dead or wounded so far.
According to IDF soldiers speaking of their experiences in a +972 report, they tend to say every male they kill is a Hamas terrorist. In one instance two separate IDF groups each individually chalked up the same Hamas kills. Over-counting deaths as Hamas deaths may be the reason why so many Hamas are apparently still fighting even after nine months of being bombed, and shot, and 38,000 thousand
bodies mounting up.
