With all the chatter in the news about this (now 14000 strong) migrant caravan moving to the US, and Trump sending 800 troops to the border..
What do YOU think the troop's roll should be?

Should they be there for just logistical, medical and legal aid?
Should they be there for 'overwatch"?
Should they have more of a hands on approach, and if needed, use force to turn the caravan back?
