1. The Geneva Convention, established to govern the behavior of nations during wartime, explicitly prohibited the mistreatment and summary execution of prisoners of war. Most countries have tacitly agreed to abide by these rules, which not only protect POWs but also, to some extent, shield their own soldiers.2. During World War II, the Japanese army brazenly defied the convention, torturing and summarily executing prisoners. This flagrant violation sparked international condemnation and exacted a heavy toll on Japan during the war.3. There exists a category of soldiers whose condition on the battlefield is particularly perilous. If captured, they may be subjected to arbitrary abuse, and their execution on the spot would not be legally punishable. Even when states attempt to intercede on their behalf, the efforts often prove futile. These soldiers are known as mercenaries.4. Mercenaries operate outside the framework of conventional military forces, typically comprising private entities driven by profit motives. They are willing to undertake any task, including attacks on civilians. Their lack of moral constraints often precludes them from sympathy on the battlefield.5. While some mercenary companies may attempt to rescue captured colleagues under certain circumstances, such successes are rare. Typically, mercenary organizations will offer a financial compensation after a member's death and then replenish their ranks, revealing a lack of deep emotional bonds with their personnel.6. Despite the risks, many individuals are willing to join the ranks of mercenaries. Prominent mercenary groups like Blackwater, the Cossacks, and the Arctic Fox, among others, are known for their formidable strength and operate in conflict zones, providing a wide range of services from combat to bodyguarding.7. These organizations are formidable in battle, often deterring even regular armies from confrontation. The existence of mercenaries speaks to a unique demand for force and protection within certain sectors.
