How many angular measurement devices does the 105mm gun have for redundancy?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (C)

Redundancy in angular measurement is about having backup instruments to ensure aiming information is always available and trustworthy. For a 105mm gun, aiming requires reading angles in two directions: elevation (up and down) and traverse (left and right). To keep aiming reliable even if one instrument fails or drifts, each axis has a primary device plus a backup, and those readings can be cross-checked with each other. That setup results in four angular measurement devices in total. With four devices, the crew can maintain accurate sighting and continue firing effectively even if one instrument is out of calibration or damaged.
