Abstract : Major Held's article, 'Zeroing In,' from the May-June 1995 issue, has done a good job of highlighting the issues the Armor community must consider when selecting or modifying tank gun calibration procedures. A key element of Total Quality Management is continuous improvement, and improving hitting probability certainly is a worthwhile goal. This policy decision is ultimately one to be made by the user, within the constraints of cost and complexity, based on the best information available. The performance of the 120mm gun system during Desert Storm would appear to provide a measure of effectiveness of the current policy. There is always the question 'Can we do better?' As Major Held suggests, to make rational decisions one must know the relative magnitude of the individual error sources and the cost of correcting that error. Current calibration policy has its genesis in a pioneering series of user tests and experiments carried out by the Armor and Engineer Board during the 1970s. The principal investigators were (then) Captains Jim Brown and Bob Kloecker with analytical support by Dr. Charlie Leake. The effort began with a complete analysis of various boresighting schemes and progressed through the characterization of boresight/zero relationships.
