Shows you don’t know SQUAT!
These are fairly common terms in the US Government’s classified information handling procedures.
Read into - Given a document to sign saying you will abide by the terms of the classified program you are about to be given access to based on your need to know.
Read out of - Given another document you must sign when you no longer have a need to know for the classified program and must NOT divulge what you know.
Signing these means you are acknowledging you can and will be prosecuted should you divulge classified information. Soldiers and Marines in the field do not sign such documents for regular combat.
I think you’re a troll and a “wannabe” who is extremely jealous of real men. Project much?
