improvised explosive device – An IED is a homemade device incorporating destructive, lethal noxious, pyrotechnic or incendiary chemicals and designed to destroy, incapacitate, harass or distract. It may incorporate military materials, but is normally devised from nonmilitary components. The term is applied to a variety of explosive devices, such as bombs and mines. The term IED is acceptable in subsequent references, but only if the available facts are detailed enough to allow avoiding use of the jargon term entirely; opt for the homemade bomb, roadside bomb or the appropriate plain-English term.
Inauguration Day – Capitalize only when referring to the total collection of events that include the inauguration of a U.S. president. Lowercase in all other uses: Inauguration Day is Jan. 20. The inauguration day for the change has not been set.
infant – Use for children through 12 months old.
installation names – In running text, fully write out the name of an installation each time it appears to facilitate reader comprehension. For example, use McConnell Air Force Base on each reference as opposed to McConnell AFB. For the purposes of search engine optimization, installation names may include acronyms or be written out fully, whichever yields better search results, in URLs, metadata and in H1 for each installation page on the MilitaryINSTALLATIONS website.
internet – Lowercase. Note: The web is a subset of the internet and the terms are not interchangeable.
