I am a special soldier in TV series. Why are they still fighting drugs? Isn't the PLA foreign? Do special forces still do this?

Novels generally have exaggerated elements, because "I am a special soldier" is not a pure entity novel after all. Actually, the special forces are not so mysterious. Seeing his photo, I feel that the training is a little more than ordinary troops, but the words on it are still quite shocking. "The most comfortable day here was yesterday." My friend was discharged from the army in Xinjiang because of a gunshot wound, so there were some things about rescuing hostages on TV. If it is poisonous, it seems that TV is only responsible for catching drug lords. That drug Lord is a threat to social stability, so it is normal to request special forces for support.
