A heartwarming moment was caught on video as an Alabama high school student's Air Force father returned from Japan to see his son graduate. 

Branden Jackson was seen walking across the stage as he graduated from Huffman High School in Birmingham during one of the biggest moments of his life. 

But the special day became that much more unforgettable after the graduate was met with his father - Air Force Master Sergeant Tobias Jackson who had returned from three years of deployment in Japan - at the other end of the stage. 

'It's been very hard to keep it under wraps,' Master Sergeant Jackson told WVTM 13. 

'He's grown into such a great young man, and he understands the significance of what we do and how we do it. When he thought I was not going to make it, his response was, "I completely understand."' 

Jackson, with his diploma in hand, was seen completely stunned by the surprise, as the crowd erupted into cheers while the father and son embraced. 

'It took a lot of planning, but I definitely was not going to miss this,' Master Sergeant Jackson continued. 

'I knew this was a very large milestone, more than what people think.... Just to fly for 36 hours, I'm a little bit jet lagged still... I wasn't going to miss this for the world. 

'Heart pounding... probably one of the most proudest of my life.' 

For Jackson, the momentous day left him at a loss for words. 

'When I first saw him, I didn't recognize him... I saw the face and it was amazing,' the graduate told the outlet. 

'I don't even know how to explain it.'

His father's return was also not the only surprise in order for Jackson, as his father gifted him a new car the day after Jackson got his driver's license. 

After officially graduating, Jackson told the outlet he plans on following in his father's footsteps and joining the Air Force, focusing on cybersecurity. 

While Master Sergeant Jackson is set to fly back to Japan on Tuesday, their memory of Jackson's graduation will last forever.
