Brinks Selects

Brink’s U.S. has selected Liberty Ammunition as the provider for the duty loads used by its executive protection teams.

“We support several executive protection teams. It’s always gratifying to receive professional feedback on the effectiveness of Liberty Ammunition technology,” said Gary Ramey, CEO of Liberty Ammunition. “We are honored to also support the oldest security firm in the world. Brink's has provided protection of assets since 1859. We look forward to providing them with our latest technology.”

Liberty Ammunition’s innovation shows in the more than 15 patents it holds. The company was established by P.J. Marx in 2005 in Bradenton, Fla., where its operation remains.

One of those patents, applied for in 2005, is a rifle bullet design with a copper slug, steel core penetrator and reverse copper jacket. The intellectual property rights were officially granted in 2010, the same year the U.S. Army began issuing its M855A1 enhanced performance 5.56 NATO cartridge.

Marx sued for patent infringement, and after producing non-disclosure documents signed by military officials and vendors who tested his bullet, the court ruled in his favor in 2015. Afterward, the Army began paying 1.4 cents per infringing bullet it produced.

Unlike today’s bulletproof armored cars wearing the company Brinks logo, in the 19th century, the company's guards were behind the wheel of a horse-pulled wagons. Cash wasn’t the cargo when it first began delivering parcels across the Windy City. That service began in 1891 with the two sacks full of silver dollars it delivered.

Today Brink’s is international, with more than 1,000 branches in over 100 countries. Brinks U.S. now offers everything from secure shipments, home security, document destruction and continues its more familiar cash handling and transfer services. Brink’s was established as the Brink’s Chicago City Express Company in 1859 by Perry Brinks. It has grown since and is now recognized as one of the world’s foremost in security services and products.
