Timeline types define how events unfold in time during fire support planning. The option that may use any weird combination is a nonstandard timeline, because its defining feature is the absence of a fixed pattern. It accommodates irregular sequences, overlapping actions, and irregular durations to fit unique operations. This flexibility is essential when coordination requirements don’t align to a simple flow, such as when multiple tasks must be interwoven or timing is dictated by dynamic battlefield conditions. In contrast, a continuous timeline assumes a steady, unbroken progression of events with consistent timing; an interrupted timeline includes planned pauses but still follows a recognizable pattern with defined breaks; an ATO timeline is tied to the structured windows and sequencing dictated by the Air Tasking Order and tends to be more standardized. Therefore, nonstandard timeline is the one that accommodates those unusual combinations.
