Defence Secretary Ben Wallace defended plans to cut the number of troops as he announced an updated plan for the military on Tuesday.
As of April 1 this year, there was 79,006 full-time trained personnel in the army, compared to 82,216 in April 2015 and 98,600 in April 2012.
“We need more personnel, not less, and relying on veterans and reserve forces is no substitute for a regular, professional Force,” he said.
Labour MP Stephen Doughty said the numbers “are simply not there to deliver on that diversity and range of threats.”
Mr. Wallace responded by saying he does think an army of “73,000 is enough to meet today’s threat.”
Responding to similar concerns raised by Conservative MP John Baron, Mr. Wallace said what’s “really important” is “we have to make sure that whatever we put in the field is properly equipped and enabled, and is effectively 360 degrees.
“We therefore have to be honest about the size of our defence budget envelope. There is no point pretending that we can have huge numbers without a defence budget to match,” he said.
