So can we say that 1/3 of the combatants have been eliminated or scared off or is it a dent in the hardware?
I hate to say it, but in the big picture not many militants have been killed. The ones that were are mostly low level, the higher ups are all in bunkers. Israel isn't going after the body count on the other side, they want to destroy the infrastructure, i.e. remove their tools.
Palestinian Islamic Jihad's Quds brigades have 3,000+ fighters, most of them highly trained. They have lost less than 100 in battle.
