hmmm…

Marines

The US will deploy 5,000 troops to the southern border …

The troops, mostly military police and engineers, will come from roughly 10 US Army bases, the Journal reported.

…and……

US Marines will also be deployed.

Do NOT call a Marine a "troop" if you want to stay standing vertical.

Question is, how many Marines?
