The third party external link pattern is used to notify a user that the action they are taking will take them to a new external website.
Use this pattern when the user is in the middle of a task or application to let them know that the action they are taking will move them away from the current site and or process. This serves as a warning where the user can then decide to remain where they are in the application or process.
Any non .gov and .mil links will be treated as external whether they belong to a government agency or not, no exceptions
