The U.S. Army returned Thursday to the Brownwood airport, where the 21st Cavalry Brigade will complete the training of a National Guard helicopter attack unit from North Carolina.

“They’re driving in now,” airport manager Sharlette Bain said Thursday morning.

The 21st Cavalry, from Fort Hood, will use the Western Training Area to train the 1st Battalion, 130th Aviation Regiment of the North Carolina National Guard.

The two units were in Brownwood from May 5-18. They are expected to remain through the end of June, local officials have said.

Last month’s operations at the Brownwood airport got off to a rough start as about 500 soldiers and about two dozen Apache Longbow helicopters arrived. On May 7, a truck in a National Guard convoy rolled over on U.S. 183 South just inside Early city limits, injuring the driver and passenger.

The night of May 8, a powerful thunderstorm generated high winds that knocked down the soldiers’ tents on the north edge of the airport and damaged several helicopters. The soldiers relocated to Camp Bowie for the remainder of their training in May.

“It’s got to be better than last time,” said Brad Locker, a member of Brownwood Chamber of Commerce’s Military Affairs Committee.
