The 1970 serial ''[[Inferno (Doctor Who)|Inferno]]'' sees the [[Third Doctor]] visit a parallel universe. In this reality, Great Britain is a fascist republic, where the Royal Family was executed for treason in 1943, as depicted in the novel ''I, Alastair''; the novel also shows that this universe's leader of Britain was an associate of [[Oswald Mosley]], and eventually became leader of the country following the downfall of the old order, with his picture being visible in the Brigade Leader's office in ''Inferno''. The parallel version of the British contingent of UNIT is an [[SS]]-like state paramilitary organisation known as the '''Republican Security Forces''' (RSF), manning their version of the drilling project as a "scientific labour camp".

They are armed with a mixture of Soviet and German weapons, such as the [[SKS]] rifle and the [[Walther P38]] pistol. Their rank system uses titles based loosely on that of the [[British Union of Fascists]]: Sergeant Benton is Platoon Under Leader Benton, Brigadier Lethbridge-Stewart is Brigade Leader Lethbridge-Stewart, and Elizabeth Shaw, a soldier rather than a scientist in their dimension, has the rank of Section Leader (which appears to be an officer rank). Their uniforms consist of contemporary US Army olive green military fatigues for Other Ranks, tan uniforms with black rank slides on the shoulders (based on the [[Sturmabteilung|brown shirts]]) for officers, and black garrison caps with white piping and an RSF cap-badge as head-dress for both. The organisation has full authority to interrogate, court-martial, and formally execute prisoners as they see fit under the "Defence of the Republic Act, 1943".

By the end of the story, most of the members of the RSF are killed when a volcanic cataclysm engulfed Great Britain and left much of their world devastated.<ref name="inferno"/>
