Oshkosh Defense and Armed Forces Foundation to Raise Funds at December 7th Green Bay Packers Game

Oshkosh Defense, a division of Oshkosh Corporation (NYSE:OSK), is supporting the Armed Forces Foundation’s (AFF) Rumble With a Cause sweepstakes as it partners with the Green Bay Packers and the Wisconsin National Guard to sponsor the Green Bay Packers’ Military Appreciation Game. Game attendees will get an up-close look at an MRAP All Terrain Vehicle (M-ATV) and have the chance to participate in the Rumble With a Cause sweepstakes.

In an effort to raise funds to support active and retired members of the U.S. military and their families, the AFF launched the Rumble With a Cause sweepstakes in October 2009 with the support of Oshkosh. AFF employees will be on site throughout the event to collect donations. The sweepstakes will have two winners, each receiving a custom-painted Harley-Davidson^® Fat Boy^® motorcycle, donated to the AFF by Oshkosh Defense. The sweepstake closes in April 2010.

"We are thrilled to collaborate with these two outstanding organizations to show our gratitude and appreciation to members of the U.S. military,” said Andy Hove, Oshkosh Corporation executive vice president and president, Defense. "We hope to generate visibility for the Foundation and the great work that they provide to military families and to raise significant donations at the game to help our troops.”

Other activities during the game include giveaways to all game attendees, the national anthem performed by a local Army soldier who will be retiring soon after 20 years of service, and video greetings from Wisconsin National Guard members in Iraq and Afghanistan. Also, four individuals and their families, two from the Wisconsin Army National Guard and two from the Wisconsin Air National Guard, will be recognized on the field during a brief halftime ceremony.

In addition to on-site entries, tax-deductible donations to Rumble With a Cause can be made at www.rumblewithacause.org (no donation or purchase is necessary to enter). Individuals will receive one entry for each $10 donation made up to a total of $200 or 20 entries. All rules, including instructions for entry without donation and eligibility requirements, are available on the sweepstakes Web site.
