First of all, tell you: the name you said is wrong. The Armed Police Force has many troops in Beijing and many kinds of police. There is no such name as "Beijing Armed Police Detachment". There is only the name "Beijing Armed Police Corps". The Beijing Armed Police Corps has more than 10 detachments. Only the 13 detachment nicknamed "Special Service Detachment" is not in Daxing, but in Chaoyang District. Each detachment has a special squadron, and drug control is not under the jurisdiction of the armed police, but under the jurisdiction of the public security department. Or the border armed police have drug control. Your information is vague, so you can't answer your question accurately. Meanwhile, why do you ask this question? Some questions about the troops are confidential.
