How to sign up for the army (like the Syrian war), what are the requirements and what you need to bring. Please, I'm serious.

First of all, you have to know the local language.

Secondly, if you want to go abroad, you can go directly from Pakistan to Syria. If you go to Syria directly from China, you will be afraid of arousing suspicion from China people.

Finally, when you get to the local area, just find an "Islamic State" with a gun or a rocket launcher, explain your purpose, and it will be OK.
