The specific personnel cannot be counted. The minimum point of joining a mercenary is to have the experience of joining the army. The best way to get rid of silk in China is to go to the French Foreign Legion for gilding.

EO is relatively decent among mercenaries. There are many reasons for closing. What the United Nations doesn't like is bullshit. Competing with two American companies is the key point. Those two American companies haven't seen many bad things. EO often uses money to quell civil strife in Asian and African countries, which may be one of the reasons.
