This reminds me of the scene in Schindler's List where the Nazi officer takes a rifle out onto his balcony and amuses himself by shooting and killing some of the Jewish camp inmates. Once a group has it's humanity stripped away from it the darkest side of people will show in how they are treated.
"Combat tested" raises the sale price, even if "combat" just means murdering unarmed people who pose zero threat. That includes all the weapons that were used against peaceful protesters at the Great March of Return. This is, imo, why Israel is farming Palestinians- to improve the return on their weapons industry, which is worth about $5 bn per year. Not to mention their tech/surveillance industry.
What a disgrace, to treat other human beings like that.
