  FIRE COORDINATION EXERCISE
  F-12. The fire coordination exercise (known as FCX) is a live-fire exercise that trains and evaluates a unit’s
  ability to integrate direct and indirect fires. A fire coordination exercise is a reduced-force exercise; full-
  caliber ammunitions may be substituted with sub-caliber munitions or devices.
  F-13. The fire coordination exercise can be conducted at platoon, company or team, battalion or task force,
  and brigade levels. Additionally, the fire coordination exercise trains unit leadership by integrating available
  organic weapon systems, to include indirect and supporting fires. (See appendix I for fire coordination.)
  LIVE-FIRE EXERCISE
  F-14. A live-fire exercise (known as LFX) trains and evaluates a unit’s ability to coordinate and control more
  than one weapon system to deliver direct or indirect fires using full-caliber munitions. Sub-caliber munitions
  may be used when appropriate. Live-fire exercises train unit movement or maneuver and the employment of
  organic and supporting weapon systems. These exercises include the integration of all logistic support. A
  live-fire exercise should test the ability of the unit’s chain of command to control and distribute fires
  effectively. Live-fire exercises require demonstrated proficiency at lower echelons before conducted at
  higher echelons. (See appendix I for more on live-fire training.)
  MAP EXERCISE
  F-15. The map exercise (known as MAPEX) is a leader and staff training exercise using maps and digital
  displays portraying tactical scenarios. They provide a training opportunity providing commanders a
  technique to train their staffs in performing essential integrating and control functions without deploying the
  unit.
  Note. A rehearsal of concept (known as ROC) drill is a map exercise sub-category. Commanders
  use a rehearsal of concept drill to synchronize, align, and coordinate an exercise using maps,
  overlays, terrain models, or sand tables at the tactical level.
  MISSION READINESS EXERCISE
  F-16. A mission readiness exercise (known as MRX) is a command and staff-level command post exercise
  conducted as a culminating training event for deploying divisions and corps with subordinate brigade-level
  headquarters.
  SITUATIONAL TRAINING EXERCISE
  F-17. Situational training exercises (known as STXs) are task-based, limited exercises designed to train a
  collective task or a group of related tasks and drills. They usually include drills, leader tasks, and Soldier
  tasks. The situational training exercise provides the leader a method to train using doctrinally approved tactics
  and techniques, but unlike a battle drill, does not prescribe a method of execution. Situational training
  exercises may be modified to meet mission requirements, but are evaluated based on standards found in
  applicable task training and evaluation outlines.
  STAFF EXERCISE
  F-18. A staff exercise (known as STAFFEX) trains unit staffs to perform tasks essential to command and
  control planning, coordination, integration, synchronization, and control functions under simulated
  operational conditions. A battalion and above exercise, the staff exercise also trains staffs to function as an
  effective team exchanging information, sharing knowledge, preparing estimates, giving appraisals, making
  recommendations, preparing orders, issuing orders, and coordinating execution of orders. Staff training
  develops and sustains planning, coordination, and other staff functions related to mission requirements. Staff
  exercises are used to evaluate staff battle task proficiency.
