DELTA
Special operations acronym
Delta is the fourth letter of the Greek alphabet and is used as a symbol in some contexts.
It also stands for a landform that is triangular in shape, like an upper-case delta: a landform at the mouth of a river formed by sediment carried by the river.
In mathematics, delta represents the difference between two values.
