( CNN ) -- The U.S. military is distributing pamphlets in eastern Afghanistan in an effort to find a soldier who has been missing for more than two weeks , the military said Thursday . A soldier mans a weapon at the rear of a U.S. Army helicopter over Afghanistan in May . The Taliban has claimed responsibility for kidnapping the soldier , who has not been identified , along with three Afghan soldiers . All went missing on June 30 in southeastern Afghanistan . The military believes the soldier may have been moved to various locations , including across the border into Pakistan , U.S. military officials said . There are two versions of the pamphlets , which are in the Pashto language and were made available to CNN by U.S . Forces Afghanistan . One shows the image of an American soldier shaking hands in a group of kids with the message , `` One of our American guests is missing . Return the guest to his home . Call us at ... '' and lists a phone number . The other shows a U.S. soldier kicking down a door , and then an outstretched hand with the superimposed image of a soldier , his head and arms drooping , and the words , `` If you do not release the U.S. soldier then ... you will be hunted , '' Capt . Elizabeth Mathias , a U.S. military spokeswoman , said Thursday . Soldiers have posted and handed out the pamphlets across Ghazni and Paktia provinces over the past 24 hours , Mathias said . Days after the soldier went missing , a senior U.S. military official said , he and the three missing Afghan soldiers were captured by low-level militants and then quickly `` sold '' to the clan and network led by warlord Siraj Haqqani , who is believed to be deeply involved in the action . The Haqqani clan operates on both sides of the Afghan-Pakistani border and is well known to the U.S. military . The soldier apparently left his small outpost on his own on June 30 with no apparent means of defending himself , the official said . Taliban commander Mulvi Sangeen said the U.S. soldier visited a military post in the Yousaf Khel district in Paktika province , got drunk , and was ambushed while returning to his car . Sangeen said the soldier was taken to a safe place . Paktika and Paktia provinces are adjacent . CNN could not independently verify Sangeen 's claims . A source with the U.S. military denied the claim that the soldier was drunk . `` The Taliban are known for lying , and what they are claiming [ is ] not true , '' the source said .
