Neat new command that is purely a gameplay concession.
When a player decides they want to act as a spotter for someone firing 5"/38 or 8" shells from the fleet (or for panzers/mobile arty for that matter) they enter the command
.spot [PlayerID]. Once this command is used the spotting player gets neon red (or any verra high visibility color) tracers* on rounds fired by the person they are spotting for.
This will make it easier for the spotter to to determine which shell hits are from "his" gunner, allowing him to more accurately adjust the gunner's fire since he can easily pick it out of the lot of shells that are in the air. 3 8" turrets and 4 player manable 5"/38 guns equal alot of shells in the air to try and pick the right ones from.
(* maybe ground splash could be in the same color)
To stop spotting, the spotter gives the command
.spot (w/o any player id) and no longer sees the psychadelic tracers

A companion to the .spot command is the
.mark command for those players firing the ships' guns or other artillery pieces. Simply put, .mark sets the 'marked' coordinates to the position where that gunner's last rounds landed. This does away with the total inaccuracy of clicking on the map to mark coordinates and gives the gunner an accurate reference to where he needs to train those big guns to be in the area of his target (base icons on the map are 2-3miles/side or larger, depending on map zoom, and a base fits inside a 1/2mile square on the terrain). A spotter would still be needed to make sure rounds are landing on target and to help the gunner accurately shift fire from one target to the next on a base.
There is no companion command to reset the coordinates marked with .mark. A click on the map is sufficient to reset them.
