HKB Mammut (originally HKB Les Effards) was one of the Moerser batteries, established at Rectory Hill. The high arc of fire meant that the guns could cover the valleys and behind hills. The only concrete poured here was to construct the command bunker, which is of a similar type to the other Moerser batteries and survives beneath a house. There are no visible traces of the battery except for the command post, and virtually the entire site has been redeveloped.
