[1]S. D. Foltz, G. L. Gerdes, M. J. Hanson, D. A. Krooks, and C. C. Rewerts, "Public reporting and a more sustainable army," ERDC, Champaign, IL, USA, Rep. no. ERDC/CERL TR-09-11, Apr. 2009. [Online]. Available: http://www.dtic.mil/dtic/tr/fulltext/u2/a500705.pdf

Notes: 

The title of the report should appear in sentence case (i.e. only capitalize the first word and any proper nouns) (see p. 39, "Reports and Handbooks: Basic Online Format," 1). Abbreviate the name of the company when possible; use commonly known abbreviations or consult the list in IEEE p. 40-52 (see p. 39, "Reports and Handbooks: Basic Online Format," 1). Consider including an access date for online materials, especially if you do not know the date of publication; when the access date is used in place of the date of publication, place it immediately after the URL (see p. 39, "Reports and Handbooks: Examples," 2). For URLs, provide the link to the publisher's website whenever possible, not the link to the library database as per APA style (see pg. 38, "On-Line Sources"). If your only option is to provide the link to the database, provide the name of the database in place of the URL (see p. 40, "U.S. Government Documents: Example," 1).
