Should all citizens be required to serve in the military?

No

Explanation:

I think that all citizens should not be required to serve in the military because kids cannot serve in the military because they are young. And some people just don't want to be in the military.

Definitely not

Explanation:

While the government has the authority to “raise and support Armies,” there is no constitutional basis for compelling citizens to serve in the military,while conscripting people into the military would just make the armed forces less efficient.
