This article describes attrition formulas that (a) consider area fire and point fire, (b) consider various levels of coordination of fire, (c) allow the explicit consideration of the use of various types of munitions, (d) allow a maximum density of targets for area fire, and (e) allow meaningful allocations of fire for point fire. For each type of fire (area or point) and for each relevant level of coordination except one (shoot‐look‐shoot fire), the precise form of the corresponding attrition formula is given. © 1995 John Wiley & Sons, Inc.
