My outfit used a transit purchased from the German economy since it was superior to the old "aiming circle" issued by the Army.

Periscopic aiming circle (PAB-2M)

Must know artillery methods in direction of fire, use of fire direction instruments, such as aiming circle, BC telescope, and range finder.

Secondly, it symbolises the aiming circles provided on the ground targets as seen from the air and signifies the need for accuracy of results to be obtained during flight testing.

The day periscope sight has a unity magnification window with a collimated aiming circle and an 8x magnification sight with a ballistic reticle.

The rifle also has a slightly different optical sight that features a reticule with a fine dot in the center of the aiming circle, allowing for more precise aiming.

However, for artillery another instrument, called either a director (UK) or aiming circle (US), became widespread and eventually the primary method of orienting guns in most if not all armies.

When you went into shooting mode it went into a first-person view and you could select snap shots or aimed shots, which altered the size of an aiming circle on screen."

The day sight has a wide field of view (22 ) with x1 magnification including a collimated aiming circle, and a narrow field of view (8 ) with x8 magnification and a ballistic graticule.

While the modifications proceeded at Kirtland, airmen from Holloman AFB, on the eastern edge of the White Sands Range, replaced the seventy-foot aiming circle with a new target one hundred feet square.

At this point the gun is ready for direct fire using the OP4 direct fire sight, or can be orientated and have its position fixed via the aiming circles for subsequent indirect fire using the Pantel sight.

In some special circumstances, such as when only one round or salvo was going to be fired (e.g. by nuclear artillery or a multiple rocket launcher), a director or aiming circle about a 100 meters away could be used as an aiming point.

It comprised a R-130M radio with a 10 m telescopic antenna which could be used only in a static position as it required shrouds, an artillery aiming circle PAB-2AM and TNA-3 navigation station, all of those could be supplied by an auxiliary gasoline-fired generator.
