I've introduced you guys to Major General Arnold Punaro (USMC, retired) once before:
Through Leidos Holdings, he has a total compensation package of $2,735,249. His other sources of income seem minor in comparison - Sourcefire Inc came in at $172,239 and SAIC,Inc at $15,600, and DesignLine Corp at $149,998. He continues to give advice to the Pentagon via the Reserve Forces Policy Board and the controversial Defense Business Board.
General Punaro isn't the only rich guy serving on the Defense Business Board and, together, they recommend outcomes that would benefit the board members and their companies as much if not more than the Department of Defense:
Its 21 members know little about military affairs, but they are rich in Wall Street experience, including with some of the biggest companies implicated in the 2008 financial meltdown. They are investment bank CEOs and CFOs, outsourcing experts, and layoff specialists who promote a corporate agenda of "behavior change" and "business solutions" in the military bureaucracy. The board proposes not only to slash and privatize military pensions, but also to have the Pentagon invest in oil futures, boost pay for its executives and political appointees, and make it easier for them to fire rank-and-file employees while scaling back those workers' collective-bargaining rights.

As soon as any organization invites General Punaro to speak, be warned. They won't be talking about how to save hard earned benefits and compensation but how to cut them.
