The public is invited to the 2 p.m. Sunday homecoming at Gowen Field for the first 50 soldiers from the 1-183rd Aviation Battalion of the Idaho National Guard.
Cars will be allowed at Gowen. However, drivers of cars without Department of Defense stickers must present a valid driver's license and car registration before being allowed on base.
The homecoming is the end to an 18-month deployment, with nearly 12 months spent in Afghanistan for Operation Enduring Freedom.
The remaining soldiers from the 1-183rd are expected home within the next two weeks.
About 250 Idaho soldiers served in Afghanistan with the 1-183rd on a diverse mission that included combat missions in Apache helicopters, troop and equipment transport and providing medical care to soldiers and Afghan civilians.
It was one of the largest deployments for the Idaho National Guard since October 2001.
Some 1-183rd soldiers saw heavy fighting from a resurgent Taliban, but no Idaho soldiers were killed during the mission.
