He had already been in the spotlight for comments made public several days ago in which he asserted that he had targeted Taliban fighters from the cockpit of his Apache attack helicopter.
In interviews conducted in Afghanistan, he said that he had fired on Taliban positions: "If there's people trying to do bad stuff to our guys, then we'll take them out of the game."
After he landed, Harry emphasized that he was pleased to be home and did not elaborate on his statements about combat, although he did indicate he plans to continue being a soldier.
"Four-and-a-half months passed really quickly," Harry said. "I'm very, very happy to be back."
He said he looked forward to seeing family and friends "behind closed doors."
"The best thing is for the boys to be back and seeing their loved ones, and I'm looking to do the same," the prince said, adding that reporters would not be invited to his family reunion.
Harry also said conditions in Afghanistan were much improved compared to his earlier deployment five years ago. "The difference is fantastic," he said.
Defense officials announced Monday that Harry - known as Capt. Wales in the army - had completed his deployment as co-pilot gunner on an Apache attack helicopter.
British troops leaving Afghanistan traditionally have a short stopover in Cyprus to decompress and are provided with four bottles of beer after a long stint on alcohol-free bases.
Harry is expected to go to the headquarters of his Army Air Corps squadron before starting several weeks of leave. He said he looks forward to resuming some charity work and taking up some royal duties.
