Three native Hawaiian organizations are challenging the Army's Stryker plan in federal court, saying the service failed to consider any location other than Hawai'i for the fast-strike unit, in violation of federal environmental law.

The lawsuit, filed yesterday in U.S. District Court in Honolulu by Earthjustice on behalf of the 'Ilio'ulaokalani Coalition, Na 'Imi Pono and Kipuka, seeks to prevent the Army from going forward with the transformation of the 2nd Brigade at Schofield Barracks to a Stryker brigade.

The groups want the Army to delay the project until it expands its environmental impact statement to adequately consider "a range of alternate locations outside Hawai'i for transformation," according to a news release.
