Troops needed treatment for headaches and hearing problems after using a new British tank that has just been cleared for deployment,according to reports.
The revelations come days after a minister promised the Ajax combat vehicle had ‘left its troubles behind’.
Ajax tanks have been in development for years,but faced delays after soldiers suffered injuries from its loud noise and strong vibrations.
It was meant to enter service in 2017,but has only now declared initial operating capability (IOC),a milestone that means it can be deployed on operations.

Ajax has been through rigorous trials and an assured safety process,and the evidence shows it is safe to operate.
