And then they gave him a newly refurbished car.
Before the 25-year-old left for two tours in Iraq, Trost had spent all his savings to buy a Subaru STi electric blue sports car. He loved the vehicle, but it needed a lot of repairs that he just couldn't afford.
When the soldier arrived at the Welcome Home ceremony, he was brought to tears by the sight of his beloved car, completely restored.
"I don't have words," said Trost. "I don't know what to say."
Family, friends and even strangers donated approximately $25,000 to pay for a new paint job, struts, springs, engine upgrades, a new turbo charger, new wheels and more.
The young veteran, who survived both a bullet to the chest and a roadside bomb, was struck speechless by the town's giving spirit.
"I'm so overwhelmed, I just don't know what to say," Trost told the Associated Press. "Everyone here is so amazing and I'm so grateful."
With tears in his eyes, Trost thanked everyone who took part in the car's restoration and who welcomed him home.
