I have an intense dislake for the new catch all Tactics skill and worked out a new CODA skill. (note I obviously used some info (my paraphase and copy) from the the CODA core book and TOS Icon Core book)
Planetary Tactics (Int)
Academic; Trained
The character with this skill possesses an understanding of those tactics best employed on a planets land surfaces or in its atmosphere and is able to employ them in different environments. During combat on a planets surface the Planetary Tactics skill determines your units (squad or larger) initiative.
Sample Specialties:
Small Unit Tactics the character knows the best methods for conducting small units such as companies, platoons and squads in conventional stand up combat. These kind of combats include patrolling, raiding, defending, and attacking.
CQB this is used when combat occurs in close quarters such as the corridors of a Starship, inside a tunnel or securing a specific building. This used most often by Security personnel and terrorist.
Terrorism the character understands the use of terror (bombings, kidnappings etc.) against a civilian population in order to cause a political reaction. This specialty can be used by both terrorist themselves and counter-terrorist experts.
Other Specialties
Guerilla Warfare, Mechanized Warfare, Naval Warfare, NBC Warfare, Air defense
In Combat a tactics test is carried out by the leader of a unit when they attempt to either conduct a maneuver or bring weapon fire from more then one place onto a single target. In addition the leader can conduct a skill test to see how successful there plan for an operation is for example the PC playing a platoon leader lays out the way he intends to attack a Cardassian strongpoint, the narrator then orders the platoon leader to make a Tactics roll (or maybe several), if successful then the combat is resolved. In addition some times a plan requires many different parts played by subordinate leaders to maneuver and attack, in each case a subordinate leader will conduct such movement and may be called upon to make a tactics test as well.
If a platoon leader or whatever the rank of the leader, fails there tactics test then based upon the difficulty of the test the narrators can assigned penalties to subordinate leaders.
