Ammunition monitoring apparatus, self-propelled artillery, and ammunition carrier

An ammunition monitoring apparatus comprising:

• at least one object-position detection sensor installed near a shell or charge route to face at least one set area, the at least one object-position detection sensor configured to output position information of a shell or charge in the at least one set area, the position information including first information corresponding to a first outer edge of the shell or charge in a view and second information corresponding to a second outer edge of the shell or charge, opposite to the first outer edge, in the view;
• and
• a controller configured to determine whether a position range occupied by the shell or the charge in the at least one set area exceeds an allowable position range that is larger than a size of the shell or charge, based on the position information, including the first information and the second information, received from the at least one object-position detection sensor, and to output an alert signal indicating a poor position upon determining that the position range occupied by the shell or the charge in the at least one set area exceeds the allowable position range.
