For "The Invasion", Privates and Corporals wore , while ranks of Sergeant and above wore uniforms based on , but lacking buttons and with the jacket – which appears to be fastened by velcro – tucked into the trousers. All UNIT members wore oval patches with 'U.N.I.T' embroidered on them on their left sleeves and NCOs wore their badges of rank on their right sleeves. Sand/Beige coloured berets, similar to those worn by the Special Air Service with the black UNIT logo on a round white background as a cap badge were worn by all ranks. There was also the assault team, who wore 1960 pattern fatigues and dark berets with the same UNIT insignia. For UNIT's next appearance, "Spearhead from Space" (1970), the No.4s became uniform for all ranks, except for two radar operators seen in the opening who wear No.7s; the female officer wearing a tie with a UNIT logo printed on. The No.4 style of uniform stayed throughout "Doctor Who and the Silurians" (1970).
