Colton James Video - Jasper Supports Brave Men

Country music singer/songwriter, Colton James, has become a regular visitor at Jasper Engines & Transmissions in recent months, not only to show his support for the 190 military veteran Associate-Owners that work at our facilities, but to share information about his project Harvest 4 Heroes.

Harvest 4 Heroes helps fund the support for our wounded war veterans in providing them an opportunity to visit a retreat planned for just outside Norfolk, Virginia. This retreat will be designed to meet the needs of our wounded veterans and provide bonding opportunities for them and their families while partaking in hunting, fishing, camping and other outdoor activities.

His most recent visit was on April 5th to shoot a special JASPER® 75th Anniversary music video for his song, "Brave Men", a tribute to all who served in the Armed Forces. Some of JASPER's military veteran Associates were asked to participate in James' video, and contribute a picture of themselves in uniform for the video shoot.

"We are really excited to be at Jasper Engines & Transmissions, in the fact that you employ so many veterans across the country," said James. "One thing this video is going to stand for is going to be representing what all our brave men and women do."
