Members of the Air Force shout slogans as they protest in La Paz, Bolivia, Tuesday, April 22, 2014. Hundreds of low ranking soldiers from Bolivia's Armed Forces marched against the military high command's dismissal of four of its leaders who defended their call for more career opportunities. Soldiers who study three years to be sergeants and then warrant officers want the opportunity to rise in rank, according to Felix Jhonny Gil, president of the National Association of Warrant Officers and Sergeants. The soldiers' wives started a hunger strike in solidarity. (AP Photo/Juan Karita)
