If there is one constant in the private military and security contracting industry it is that nobody has a good record in predicting what the industry will be doing in the future. And much of the time the public is relatively clueless about what they are currently doing
In the 1980s, when the U.S. Army came up with the U.S. Logistics Civil Augmentation Program (LOGCAP) program to help provide logistics support to U.S. forces globally nobody foresaw just how massive that support would become in Iraq or Afghanistan, let alone the major presence of gun-toting private security contractors. Until the revelations of Edward Snowden, most of the public was unaware about just how much the intelligence community depended on private contractors.
The only thing one can say with reasonably certainty is that if there is a way to make money off of it private contractors will be there to make a contract bid. So, now that Iraq is mostly a memory for contractors, although the threat of ISIS is bringing up the numbers a bit, and Afghanistan is trending downwards to the inevitable zero it is a good time to ask what other things private contractors are into these days, aside from logistics and security details.
