A Combat results table or a CRT is used in wargaming to determine the outcome of a clash between individual units within a larger battle.
[1] Game conditions can influence the strength numbers used to calculate the ratio in the form of doubling or halving each of them, in addition to column shifts that can occur due to terrain, weather or some other factor.
Typical results include elimination, advances or retreats, surrender, casualty reduction, or partial losses.
For example, the simple Combat Results Table (CRT) included in this article could be interpreted as follows: The brackets seen in the results running diagonally from the lower left hand corner of the chart to the upper right hand corner could indicate some additional outcome such as melee or continuing engagement that involves both sides.
As wargames typically use a standard 6-sided die the addition of numbers below 1 and above 6 in the left hand column would indicate this game uses what are called die roll modifiers to reflect further special conditions, such as defender’s terrain, weather, leadership, training, morale, surprise, experience levels, or supply conditions, etc.
