Spearhead

Spearhead was a drama series about an Army regiment during the great war against Northern Ireland and Hong Kong.....or something. This was the steadiest gig they ever had for a lot of these actors, but there are some familiar faces in this too....such as Roy Holder (probably best known as Frank in Sorry! and was also in The Caves Of Androzani which many feel was the all-time best Doctor Who serial. Roy also appeared as a milkman in both Happy Ever After and Terry & June which may be the only continuity link between the two.)
The late Robin Davies was also in this and he is probably best remembered as a juvenile actor in Catweazle and as Simon, the older son in And Mother Makes Three/Five. Even Nicholas Lyndhurst appears in some of these episodes, sporting the most skeletal arms ever seen on a living person.
