Members of Troop C, 1st Squadron, 113th Cavalry, in Le Mars, are hosting the benefit for Jeremy Henrich, of Hinton.
Dollars raised will go directly to Henrich to help medical bills, which accumulated after he was hospitalized and treated for heart complications in October.
"My heart sends out extra electrical signals," Henrich explained. "It went off and I went into cardiac arrest and then was hospitalized."
He was put into a chemical-induced coma for about four days and also had surgery to correct the problem, Henrich said.
"So far everything seems good," he said. "Hopefully everything stays good."
Sunday's free-will offering pancake breakfast will be 7-11 a.m. at the Armory, 1050 Lincoln St. N.E., Le Mars.
Pancakes, eggs, bacon and refreshments will be served.
Spouses and family members of the 113th Cavalry soldiers will be cooking and serving at the benefit.
"We're volunteering our time and doing it for them," said Penni McIntosh, one of the volunteers, referring to the local Guard troop. "We're the manpower."
She added that since it is the 113th Cavalry's weekend for training exercises, members of the troop will be "in and out" during Sunday's benefit.
Along with food, the benefit will also have a drawing for prizes donated by local companies.
In addition, there will be a bake sale Sunday which is intended to raise dollars to host future events for 113th guardsmen and their families, McIntosh said.
"We're trying to get money for all the families in this unit, too," she said. "We want to support all of them."
Henrich, who returned last year from a year-long deployment in Afghanistan with the 113th Cavalry, said he also wants to give back to Guard members.
"If there is anything extra from the benefit, I'm giving it (those dollars) back to the Family Readiness Group," he said.
