The US Army has placed a sizeable order with Mack for heavy-duty tractors and trailers.

Mack has received a US$28.5 million order from the US Army TACOM Life Cycle Management Command for 152 Mack Vision Elite model tractors (known as the Pinnacle Axle Back model domestically) as well as 152 35-tonne lowboy trailers.

The Mack Visions will come with 70-inch high-rise sleepers. Spare parts are also included in the deal, Mack announced.

'Mack is extremely pleased with this opportunity,' said Dennis Slagle, Mack president and CEO. 'We've earned our corporate symbol, the bulldog, by providing tough, tenacious trucks for more than a century. The products we offer today retain that same level of durability and reliability, but feature a level of engineering, technology and comfort that customers 100, 50 or even 10 years ago would not have imagined.'
