Royal Marines know how to advertise to stir the passions of young men. None of the bullshit running to the sound of chaos to deliver "meals on wheels", they instead show rough conditions, talk about working through hunger and fear, and lastly show their guys going up against scum that need to be eradicated.
The USMC once did it that way too. Hopefully we'll get back to that with a new Commandant in less than a month.
