Answer:
Pro: Getting your voice heard, and swaying the public opinion about the war efforts.
Con: Decrease the morale of the soldiers who are already stationed, if the protest is negative, and the government may keep an eye on you as well.
Explanation:
When it comes to protesting against a war that is already ongoing, it could go either way, as to whether or not the protest would have the intended impact. If the war has been going for a long time and there isn't exactly a clear reason as to why it is still going on, public opinion tend to be more sympathetic - for example: Vietnam War protests. However, just like during the Vietnam War, it can damage the morale of the soldiers who are already there and as history has proven, the government might put you on the list of people-to-watch - just like past celebrities who have protested against the Vietnam War such as Jane Fonda.
