The 2021 T20 Inter Services Championships will be played at Arundel Castle in West Sussex later this year.
The men's tournament was due to be played at its regular location at Lord's Cricket Ground in London but scheduling conflicts have meant the action must be moved for a year.
The military has been invited back to Lord's for the 2022 competition.
Mike Thornley, Secretary of UK Armed Forces Cricket Association and Army Cricket Association, explained why the decision was made.
He said: "This year, we'd hoped to play at Lord's. That was always the plan.
"It's entirely due to coronavirus and rescheduling of test matches and counties, which obviously take priority.
"We just couldn't find a date that we could be sure we could make it work at Lord's this year.
"The good news is that Lord's have very kindly said that they will invite us back next year. So, hopefully, we will back to normal."
He added: "In the interim for this year, what we've managed to do is arrange that the men's Inter Services T20 Championship will now happen at Arundel on 10 September."
Mr Thornley was also pleased to announce that plans are in place for a full programme of Inter Services cricket in 2021.
"In addition to the men playing at Arundel, the ladies' sides will also play a T20 at Arundel," he said.
"The development side will play a T20 and both the men and ladies will play the longer format (three-day games) which will take place [at Aldershot] and Vine Lane."
As well as tri-service matches, the Army is also scheduled to face off with the Hampshire development team in September, just before the Inter Services T20.
