----------------------------------------------- FORMER 'pentagon employee' eh . well feck him too WP !!`yup, they technically volunteered twice, although units are volunteered by commanders. so you could say they all individually volunteered when they joined up. but volunteered by representation of their command, which they individually volunteered for, to do the mission.
Quit with your nonsensical semantical meanderings. Troops go where they are ORDERED to go. They took an oath to that extent. The CO doesn't mail all army staff in the US asking for volunteers.
The vets have their own take on this too; "Former Pentagon Spokesman: This Is Not An ‘Invasion’ — And The Military Doesn’t Need To Go To The Border."
