Providing America’s military and first responders with equipment is a big job, and that’s why the government created the Global Services Administration, also known as GSA. This program allows for defense contractors to provide that tactical equipment and other gear that these brave men and women need to do the tough jobs they do. Buying equipment and gear like FES (fire and emergency services equipment) is a huge responsibility, but not an insurmountable one — especially when you know where to look and how to buy.
