Are you assuming these are the folks being sent vs. "other" troops, or have you seen it mentioned? I haven't seen any indication that we are sending experts in medicine/disease (could have missed it), and most of the stories surrounding it do not seem to think this is the case or they would not be so outspoken against it.
Will grant that not all troops are combat troops, but the sense I have been getting is that many of those who will be sent are not "designed by training" for the role they will be filling.
Your statement was that all the military does is combat, it obviously isn’t.
Post 24 gave a little bit of what these troops are for.
“The key elements of military response will focus on logistics, supplies, engineering, support for the Accra, Ghana, air bridge for transport of supplies and personnel to the epidemic, and the construction of at least 17 new hospital facilities designated for Ebola care.
The military will also build a training facility, which will rapidly teach infection control and self-protection procedures to hundreds of local and foreign health workers. The military hopes to process up to 500 health workers, both civilians and humanitarian responders, in a week.”
