"I think we [the British Army] are too small ... We do need to grow ... We’re in a fortunate position here," Radford said in an interview with UK media.
"We’ve got a position of influence right across NATO. I worry that if we don’t invest and we don’t build up our industrial base and we don’t lead as we should, we might lose that position."
The general noted that Russia's special military operation in Ukraine showed that technological advancement cannot be at the expense of personnel, adding that "equipment is only as good as the people that are managing and operating it."
"I think we’ve had a slight awakening after Ukraine, but we need to do a twin track approach. We need to stay at the leading edge of innovation and technology and lead on that as much as we can. But at the same time it needs to be underpinned with hard fighting power," Radford argued.
"If someone comes toward you with a tank, you can’t cyber it away. You can’t cross a bridge with cyber. It needs to be balanced."
