A group opposing the army's planned expansion of a training site in southeastern Colorado is conducting a news conference this morning outside Denver's Federal Courthouse.
Afterward the group, called "Not 1 More Acre," will file a lawsuit asking the military to disclose the expected environmental, cultural and socioeconomic impacts of the expansion of the Pinon Canyon Maneuver site.
The army's proposal would almost triple the size of the site to about one–thousand square miles.
The army says it needs the room to train more soldiers on new weapons and tactics.
Opponents say the army hasn't demonstrated that it needs the expansion.
They worry about the effects on the economy if the land is lost to agriculture.
The site is used by soldiers at Fort Carson.
