1. A live fire exercise or LFX is any military exercise in which a realistic scenario for the use of specific equipment is demonstrated. In the popular lexicon this is applied primarily to tests of weapons or weapon systems that are associated with the various branches of a nation's armed forces, although the term can be applied to the civilian arena as well.
2. Joint exercise: Several different armed forces training together are called having a joint exercise. Said forces may be different branches of the armed forces from one country or may be armed forces from different countries.
3. Military simulation: Other types of exercise include the TEWT (Tactical Exercise Without Troops), also known as a sand table, map or cloth model exercise. This type of exercise (in recent years assisted by computer simulation) allows commanders to manipulate models through possible scenarios in military planning. This is also called warfare simulation, or in some instances a virtual battlefield and in the past has been described as "wargames." Such examples of modern military wargames include DARWARS, a serious game developed since 2003 by the US DARPAagency with BBN Technologies, a defense contractor which was involved in the development of packet switching, used for ARPANET, and which developed the first computer modem in 1963.
4. Field exercise: The more typically thought of exercise is the field exercise, or the full-scale rehearsal of military maneuvers as practice for warfare. Historical names for field exercises in the Commonwealth include 'schemes.' In a field exercise, the two sides in the simulated battle are typically called "red" and "blue", to avoid naming a particular adversary
5. Military drill - training in marching and the use of weapons:

• practice session, practice, drill, exercise, recitation - systematic training by multiple repetitions; "practice makes perfect"
• military training - training soldiers in military procedures
• close-order drill - (military) military drill of troops in standard marching (shoulder-to-shoulder)
• square-bashing - drill on a barracks square
• armed forces, armed services, military, military machine, war machine - the military forces of a nation; "their military is the largest in the region"; "the military machine is the same one we faced in 1991 but now it is weaker"
• Military Sentinel: Kampong Speu – The United States and Cambodia today commenced Angkor Sentinel, an annual military exercise designed to  promote regional peace and security. U.S.
