A military installation infobox may be used to summarize information about a military structure or facility, such as a fortification or military base.    The infobox should be added using the  template, as shown below:  {{তথ্যছক সামরিক সংস্থাপন | name =  | ensign =  | ensign_size = | native_name =  | partof = <!-- for elements within a larger site --> | location =  | nearest_town = <!-- used in military test site infobox --> | country =  | image =  | alt =  | caption =  | image2 = <!--secondary image, major command emblems for airfields --> | alt2 =  | caption2 =  | type =  | coordinates = <!-- {{Coord}} --> | gridref =  | image_map =  | image_mapsize =  | image_map_alt =  | image_map_caption =  | pushpin_map =  | pushpin_mapsize =  | pushpin_map_alt =  | pushpin_map_caption =  | pushpin_relief =  | pushpin_image =  | pushpin_label =  | pushpin_label_position =  | pushpin_mark =  | pushpin_marksize =  | ownership = <!-- government department such as the MoD or the United States DoD --> | operator = <!-- where different from ownership such as the RAF or the USAF --> | controlledby = <!-- such as RAF Bomber Command or the Eighth Air Force --> | open_to_public = <!-- for out of use sites/sites with museums etc --> | site_other_label = <!-- for renaming "Other facilities" in infobox --> | site_other = <!-- for other sorts of facilities – radar types etc -->   | site_area = <!-- area of site m2, km2 square mile etc --> | code = <!--facility/installation code, applies to US --> | built = <!-- {{Start date|YYYY}} --> | used = <!--{{End date|1946}} --> | builder =  | materials =  | height = <!-- height of tallest part, not above sea level --> | length = <!-- for border fences or other DMZs --> | fate = <!--changed from demolished parameter--> | condition =  | battles =  | events =  | current_commander = <!-- current commander --> | past_commanders = <!-- past notable commander(s) --> | garrison = <!-- such as the 25th Bombardment Group --> | occupants = <!-- squadrons only --> | designations =  | website =  | footnotes = <!-- catchall in case it's needed to preserve something in infobox that doesn't work in new code --> }}  The following supplemental blocks may be copied into the template above as needed, just prior to the "footnotes" parameter.

For proper grammar, it may be necessary to insert "the" before the name used here.  location – the geographical location of the installation.  image – optional – an image of the installation.  The image must be given in the form [[File:Example.jpg|300px]]; in particular, the thumb attribute must not be selected.  caption – optional – the text to be placed below the image.  map_type – optional – the base map to be used for the location map, e.g., "Scotland"; see  for more details.  map_relief – optional – set to any non-blank value to use a relief map (if available).  coordinates – optional – latitude and longitude for placing the marker on the location map. Use ; see the Coord template documentation for details.   gridref – optional – map grid reference.  map_size – optional – width of the location map in pixels (px), e.g., "150"; defaults to "220".  map_alt – optional – alt text for location map; see Wikipedia:Alternative text for images.  map_caption – optional – caption displayed below the location map; defaults to "Shown within ", e.g., "Shown within Scotland".  type – optional – the general type of installation ("Castle", "Fortress", "Bunker", "Military base", "Wall", "Defensive line", etc.).  code – optional – the location or facility code, such as the ILC or ILK code.  built – optional – the date when the installation was built, usually given in years.
