4-year-old Riley Holsapple is smiling from ear to ear.

Her dad, Sgt. Adam Holsapple, is home after spending the past 9 months in Kuwait.  He is with the 1st Armored Brigade Combat Team, 4th Infantry Division at Fort Carson.

Sgt. Holsapple returned to Colorado Springs Wednesday night, but Riley had no idea until he surprised her at Bear Creek Regional Park Thursday.

Watch the happy reunion in the video player above.
