How the Chinese military uses ‘human abacuses’ to counter smart device failures
State media says PLA abacus programme aids infantry and artillery units in determining optimal firing times and helps soldiers keep focus
China is harnessing an ancient mental calculation technique to train soldiers as “human abacuses” for high-stakes combat scenarios where advanced technology might fail.
The state broadcaster showed a recent drill simulating radar failure in which Xu predicted the trajectories of three targets in just seconds by analysing their direction, altitude and speed using mental mathematical techniques and analogue tools. Her calculations enabled precise targeting, showcasing the technique’s effectiveness, CCTV reported in the programme first aired in August.
The programme highlighting Xu’s skills has been aired repeatedly, aligning with China’s high-profile Victory Day grand military parade on September 3 and National Day celebrations on October 1, moments designed to bolster domestic confidence.
