Glossary
geospatial engineering
(Army) The art and science of applying geospatial information to enable understanding of the physical
environment for military operations. The art is the ability to understand mission, enemy, terrain and
weather, troops and support available, time available, and civil considerations (METT-TC) and the
geospatial information available, including intent of use and limitations, in order to explain the
military significance of the terrain to the commander and staff and create geospatial products for
decision -making; the science is the ability to exploit geospatial information, producing spatially
accurate products for measurement, mapping, visualization, modeling, and all types of analysis of the
terrain. (FM 3-34)
insurgency
An organized movement aimed at the overthrow of a constituted government through use of
subversion and armed conflict. (JP 1-02)
measure of effectiveness
A criterion used to assess changes in system behavior, capability, or operational environment that is
tied to measuring the attainment of an end state, achievement of an objective, or creation of an effect.
(JP 3-0)
measure of performance
A criterion used to assess friendly actions that is tied to measuring task accomplishment. (JP 3-0)
METT-TC
A memory aid used in two contexts: (1) in the context of information management, the major subject
categories into which relevant information is grouped for military operations: mission, enemy, terrain
and weather, troops and support available, time available, civil considerations (2) in the context of
tactics, the major factors considered during mission analysis. (FM 6-0)
mobility operations
Obstacle reduction by maneuver and engineer units to reduce or negate the effects of existing or
reinforcing obstacles. The objective is to maintain freedom of movement for maneuver units, weapon
systems, and critical supplies. (FM 3-34)
nonlethal fires
Any fires that do not directly seek the physical destruction of the intended target and are designed to
impair, disrupt, or delay the performance of enemy operational forces, functions, and facilities.
Psychological operations, electronic warfare (jamming), and other command and control
countermeasures are all nonlethal fire options. (FM 6-20)
OAKOC
A memory aid associated with the five military aspects of terrain: observation and fields of fire,
avenues of approach, key and decisive terrain, obstacles, cover and concealment. (FM 6-0)
PMESII-PT
A memory aid for the varibles used to describe the operational environment: political, military,
economic, social, information, infrastructure, physical environment, time (operational variables). (FM
3-0)
priority intelligence requirement
An intelligence requirement, stated as a priority for intelligence support, that the commander and staff
need to understand the adversary or the operational environment. (JP 2-0)
reconnaissance operations
Those operations undertaken to obtain, by visual observation or other detection methods, information
about the activities and resources of an enemy or potential enemy, or to secure data concerning the
meteorological, hydrographical or geographical characteristics and the indigenous population of a
particular area. (FM 3-90)
