Fort Meade , Maryland ( CNN ) -- A military prosecutor said Bradley Manning acted as a `` determined insider '' in leaking classified information about the wars in Iraq and Afghanistan and should be locked up for 60 years at least , but the Army private 's lawyer contended he can be rehabilitated and should not `` rot in jail . '' The two sides delivered their final sentencing arguments to Col. Denise Lind , the judge who convicted Manning at trial and will now determine his punishment . He faces up to 90 years behind bars for the largest leak of classified information in U.S. history . `` There may not be a soldier in the history of the Army who displayed such an extreme disregard '' for his mission as a soldier , Capt . Joe Morrow , the prosecutor , said . His arrogance , according Morrow , meant he `` felt he alone was knowledgeable and intelligent enough to determine what information was to be classified . '' Morrow asked that Manning , 25 , serve a minimum sentence of six decades behind bars , saying his actions created grave risk , disrupted diplomatic missions and endangered lives . Defense attorney David Coombs did not ask for a specific sentence , but said his client was an excellent candidate for rehabilitation , and that he should not be left to `` rot in jail . '' `` Perhaps his biggest crime was that he cared about the loss of life that he was seeing and could n't ignore it . '' Coombs said of Manning 's decision to turn over the explosive information to WikiLeaks . `` This is a young man capable of being redeemed , '' Coombs said in final remarks . `` The defense requests , after the court considers all the facts , a sentence that allows him to have a life . '' Lind recessed the proceedings until Tuesday morning but it is not clear when she will render a decision . Manning was convicted of numerous counts in July , including espionage-related charges . He avoided a potential life sentence when Lind rejected charges that his actions aided the enemy . In addition to prison , prosecutors also want Manning to forfeit pay and benefits and pay a $ 100,000 fine . Officials indicated a single sentence would cover all of the guilty counts .
