You should hand write your references on your resume.
adelina 88 [10]
This can be taken to mean a couple of things.
Overall - no - nothing on your resume should be written in by hand. If it’s going to be included on your resume it needs to be typed in and turned in at the same time as that resume. However, it’s not unusual for people to submit their references secondary to the initial submission of their resume. In that case what you can do is list a section on your resume that’s called References and underneath state “References available by request.” If they are then requested later, turn them in typed neatly on a document that matches your resume.

Information that indicates ground air or navy force levels or dispositions is what security?
AlexFokin [52]

Information that indicates ground air or navy force levels or dispositions is <u>confidential</u> security.

Security for a country's higher organizations is essential for a nation's protection.

Serious information like the nuclear organizations, army, navy, and ground air is at a higher risk for threats and hence requires higher security.

The information in such higher organizations is kept confidential and no third person is allowed access to the code of conduct of such organizations.

If information is leaked from the ground air or from navy force levels then there can be serious consequences for it. Hence, such information is always kept under confidential security.
