Abbreviation for Total Unit Value. In TripleA, there is a TUV column in the statistics tab. Note that the TUV includes non-combat units like factories. It does not include PU's (IPC's) in hand.

The Moore AI and Dynamix AI both explicitly try to maximize enemy TUV losses and minimize it's own TUV loss.

When designing your own scenarios, it can be useful to look at the TUV. Usually, the TUV should be fairly close for each side.
