Delta (Callsign)

Delta is the fourth letter of the NATO Phonetic Alphabet, corresponding to the letter "D". The word Delta is normally used instead of that letter in all communications.

The term "Delta" was originally used as the Callsign for the first Squad in the second Infantry Platoon. A second platoon has become quite rare in ShackTac ArmA 3 videos; "Delta" is now used more often for the fourth squad in the first Infantry Platoon.

Uses

 * The first Squad in the second Infantry Platoon is almost always called "Delta". If there are players on two or more Sides of a mission, each side may have its own Delta squad.


 * In ArmA 3 videos, it is more common to see the callsign "Delta" assigned to the fourth Squad in the first Infantry Platoon.


 * If Delta Squad has any armed vehicles directly attached to it, whether for transport or close fire support, those vehicles receive the callsign "Delta Victor", meaning "Delta Vehicle". This is typically shortened to "Delta Vic" ("DV" on the map).


 * Objectives for Delta Squad are marked with the letter "D", but will be referred to as "Delta Objective", "Delta Rally", "Delta Resupply", etc.


 * In an Armored Company with no infantry present, the callsign "Delta" will typically be assigned to the fourth Tank Platoon in that company. All of the above applies equally to this tank platoon.

Examples
A "Delta Squad" appears in many ShackTac videos of the ArmA 2 era, where it was very common to see two Infantry Platoons operating together. There is no need to provide examples of such videos here.

In ArmA 3, "Delta Squad" usually appears as the fourth squad in 1st Platoon. Such examples are less common. Please add any examples below, as well as examples of atypical uses of the term "Delta".
