The derelict battery can now be found on the Royal Anglian Way which is named after the 2nd Battalion of the Royal Anglian Regiment, who refurbished it in August 1969. The path leads up the west side to the top of the Rock passing by this battery and Hayne's Cave Battery .
Assuming the artillery is far away and using the asymptotes of the hyperbolas, which are lines, to find an approximate location of the artillery. [4] A curvature correction could then be applied to get a more accurate bearing. [5] Approximate solutions can be generated using sets of metal disks whose radii differ by small increments.
Gabion: a large basket filled with earth, used to form a temporary parapet for artillery; Glacis: a bank of earth sloping away from the fort, to protect it from direct artillery fire; Gorge: opening at the rear of an outwork for access by defending troops from the main defensive position; Hill fort (New Zealand: Pa (Māori))
Towed artillery is in some cases equipped with an APU for small displacements. Self-propelled artillery is permanently mounted on a carriage or vehicle with room for the crew and ammunition and is thus capable of moving quickly from one firing position to another, both to support the fluid nature of modern combat and to avoid counter-battery fire.
The Henry Knox Trail, also known as the Knox Cannon Trail, is a network of roads and paths that traces the route of Colonel Henry Knox's "noble train of artillery" from Crown Point to the Continental Army camp outside Boston, Massachusetts early in the American Revolutionary War.

The center of octagonal concrete mounting pad on the eight floor of 131-1A (which was meant to support a depression position finder) was usually the surveyed point at the end of the baseline (and thus the precise location of the base end station). [f] A survey marker embedded in the tower's roof directly above this pad defined this point. Other ...
A computer program analyzes the track data and then extrapolates the round's point of origin. This calculated point of origin is then reported to the operator with map coordinates, thus allowing friendly artillery to direct counter-battery fire towards the enemy artillery. The system has a reported range of up to 31 miles (50 km).
