Portsmouth Women For Peace protested about symbols of war in the city by mounting a demonstration outside the D-Day Museum, Southsea.
The protest was to draw attention to the tank and gun placed outside the museum.
Group spokeswoman Lynette Rees described the weapons as ‘overtly war-like pieces of machinery’.
‘The museum says they are to draw attention to the bad effects of war but we feel they are disturbing and unnecessary,’ she said.
A handful of members from Women For Peace and South Coast Against Nuclear Navies covered the tank with paper flowers.
The demonstration was to also draw attention to a Campaign for Nuclear Disarmament rally that was due to be held in Portsmouth.
