Included within each zipfile is a FGDB (Esri 9.3) containing the following:

MGRS_GZD_10km
Military Grid Reference System (MGRS) 10km Square Identifier polygons for the specific Grid Zone Designator (GZD), for each 100,000-meter square identifier’s(100km) Grid Square.

Abstract: This is a Military Grid Reference System (MGRS) 10km Square Identifier polygon shapefile. The polygons are defined by UTM zone MGRS regions, with subdivisions into MGRS 10km Square Identifiers. The MGRS is the geocoordinate standard used by US Armed Forces and NATO militaries for locating points on the earth. The MGRS is derived from the UTM (Universal Transverse Mercator) grid system and the UPS (Universal Polar Stereographic) grid system, but uses a different labeling convention. A single alpha-numeric value references an area that is unique for the entire earth. The MGRS is used for the entire earth.

MGRS_GZD_1km
Military Grid Reference System (MGRS) 1km Square Identifier polygons for the specific Grid Zone Designator (GZD), for each 100,000-meter square identifier’s(100km) Grid Square.

MGRS_GZD_100m
Military Grid Reference System (MGRS) 100m Square Identifier polygons for the specific Grid Zone Designator (GZD), for each 100,000-meter square identifier’s(100km) Grid Square.

Abstract: This is a Military Grid Reference System (MGRS) 100m Square Identifier polygon Shapefile. The polygons are defined by UTM zone and MGRS band letters into mostly 100km MGRS regions, with subdivisions into MGRS 100m Square Identifiers. The MGRS is the geocoordinate standard used by US Armed Forces and NATO militaries for locating points on the earth. The MGRS is derived from the UTM (Universal Transverse Mercator) grid system and the UPS (Universal Polar Stereographic) grid system, but uses a different labeling convention. A single alpha-numeric value references an area that is unique for the entire earth. The MGRS is used for the entire earth.

Additionally each FGDB comes with a MGRS 100km Square Identifier polygon created by the NGA.

MGRS_100kmSQ_ID_GZD
MGRS 100km Square Identifier polygon

Abstract: This is a MGRS 100km Square Identifier polygon shapefile. The polygons are defined by UTM zone and MGRS band letters into mostly 6ºx8º polygons, with subdivisions into MGRS 100km Square Identifiers. There are no classification restrictions on this information. This information was created by the National Geospatial-Intelligence Agency (NGA) Coordinate Systems Analysis Team (SNAC). This information was created in 2009. Acronyms used in the attribute table and file name include: CM = central meridian, GZD = grid zone designator, n = northern hemisphere, s = southern hemisphere, LAT = latitude, LONG = longitude.
