Military Redditors: What is the point of announcing ahead of time where and when we will be mounting an attack against ISIS? Doesn't this just help the other side prepare a defense? | [
"The warning is given so that civilians have an opportunity to get out of the area. This type of warning is given in this situation because, even if they have all of the time in the world to prepare a defense, they can not win. If this were a war between equals, or an existential war, warning would not be given."
