If it happens that visual calls are the same for two or more ships in company or in the same port, their international call signs are used. SHORTENED VISUAL CALLS.—Shortened visual calls are constructed by omitting unnecessary numbers.  If  the  Alamo  (LSD  33)  were  the  only amphibious-type ship in the vicinity with the final digit of its hull as 3, its visual call would be Lp3. UNIT   INDICATOR   CALL   SIGNS.—Call signs   for   organized   groups/flotillas,   squadrons, divisions,  and  subdivisions  of  ships  are  constructed as follows: Subdiv-subdivision Div-this  division Squad-squadron Group/flot-group/flotilla Example:  Div—this  division By using the appropriate unit pennant with a type indicator preceding the unit pennant and numeral pennants following, you form the following visual call signs: Examples:  R  Squad  p7—Carrier  Squadron  7 D  Group/Flot  p3—Destroyer  Group/Flot  3 In calling commands and ships in the same unit, the unit indicator may be used alone. Thus, DIV alone would be the call for this division. Type  indicators  may  be  omitted  from  call  signs if  no  confusion  could  result.  If  cruiser-destroyer group  1  were  in  port  with  no  other  ship  group  1 present,   the   call   for   CruDesGru   1   could   be FLOT/GROUP  p1. To form the visual call sign of the commanders of an  organized  group/flotilla,  squadron,  division  or subdivision of ships the unit indicator is followed by the type indicator. Example: Squad  D—Commander  this  destroyer  squadron Group/Flot  CDp2—Commander  crusier  destroyer group/flotilla  2 Call signs for a group of ships associated with an individual ship that is not organized as a task unit   or   element   is   constructed   by   prefixing Subdiv to the call sign of the identifying ship. The command   call   is   constructed   by   prefixing   the ship's call to Subdiv. Examples: Subdiv  Rp6p9—USS  Eisenhower  Subdivision Rp6p9   Subdiv—Commander   Eisenhower Subdivision NUMERAL   PENNANT   CALL   SIGNS.— Listed in figure 3-6 are numeral pennant call signs for general use in tactical organizations. To form the call sign for the commander of one of these groups or units, precede the listed call with pennant 0. Thus, “Entering or leaving harbor group No. 2" is p5p2. This call includes  all  units  of  the  group,  as  well  as  the commander and subordinate commanders. To address only the commander of the group, the call sign is p0p5p2. To  call  the  commander  of  the  unit  indicated, pennant  0  may  be  used  preceding  the  unit  indicator call signs. Similarly,  to  address  subordinate  commanders, p0p0 is used. A message to all squadron commanders under a group commander could use the call sign p0p0 SQUAD. Other numeral pennant call signs may be used with type indicators to designate the type of ships in a unit. The call sign for all destroyers, for instance, is p2D. SPECIAL TASK ORGANIZATION CALLS.— Visual  call  signs  employing  numeral  flags  and numeral   pennants   are   used   only   in   flaghoist communications within task organizations. These call signs always begin with a numeral flag followed by numeral pennant(s) that indicate the number of the task  organization.  Type  indicator  may  be  used following the call sign. 3-13
