Context: warfighter information network-tactical ( win-t ) ; command , control , battle management and communications ( c2bmc ) ; and twic ) . partially offsetting the decreases were higher net sales of approximately $ 140 million from qtc , which was acquired early in the fourth quarter of 2011 ; and about $ 65 million from increased activity on numerous other programs , primarily federal cyber security programs and ptds operational support . is&gs 2019 operating profit for 2012 decreased $ 66 million , or 8% ( 8 % ) , compared to 2011 . the decrease was attributable to lower operating profit of approximately $ 50 million due to the favorable impact of the odin contract completion in 2011 ; about $ 25 million due to an increase in reserves for performance issues related to an international airborne surveillance system in 2012 ; and approximately $ 20 million due to lower volume on certain programs ( primarily c2bmc and win-t ) . partially offsetting the decreases was an increase in operating profit due to higher risk retirements of approximately $ 15 million from the twic program ; and about $ 10 million due to increased activity on numerous other programs , primarily federal cyber security programs and ptds operational support . operating profit for the jtrs program was comparable as a decrease in volume was offset by a decrease in reserves . adjustments not related to volume , including net profit booking rate adjustments and other matters described above , were approximately $ 20 million higher for 2012 compared to 2011 . backlog backlog decreased in 2013 compared to 2012 primarily due to lower orders on several programs ( such as eram and ngi ) , higher sales on certain programs ( the national science foundation antarctic support and the disa gsm-o ) , and declining activities on several smaller programs primarily due to the continued downturn in federal information technology budgets . backlog decreased in 2012 compared to 2011 primarily due to the substantial completion of various programs in 2011 ( primarily odin , u.k . census , and jtrs ) . trends we expect is&gs 2019 net sales to decline in 2014 in the high single digit percentage range as compared to 2013 primarily due to the continued downturn in federal information technology budgets . operating profit is also expected to decline in 2014 in the high single digit percentage range consistent with the expected decline in net sales , resulting in margins that are comparable with 2013 results . missiles and fire control our mfc business segment provides air and missile defense systems ; tactical missiles and air-to-ground precision strike weapon systems ; logistics and other technical services ; fire control systems ; mission operations support , readiness , engineering support , and integration services ; and manned and unmanned ground vehicles . mfc 2019s major programs include pac-3 , thaad , multiple launch rocket system , hellfire , joint air-to-surface standoff missile ( jassm ) , javelin , apache fire control system ( apache ) , sniper ae , low altitude navigation and targeting infrared for night ( lantirn ae ) , and sof clss . mfc 2019s operating results included the following ( in millions ) : .

2013 compared to 2012 mfc 2019s net sales for 2013 increased $ 300 million , or 4% ( 4 % ) , compared to 2012 . the increase was primarily attributable to higher net sales of approximately $ 450 million for air and missile defense programs ( thaad and pac-3 ) due to increased production volume and deliveries ; about $ 70 million for fire control programs due to net increased deliveries and volume ; and approximately $ 55 million for tactical missile programs due to net increased deliveries . the increases were partially offset by lower net sales of about $ 275 million for various technical services programs due to lower volume driven by the continuing impact of defense budget reductions and related competitive pressures . the increase for fire control programs was primarily attributable to increased deliveries on the sniper ae and lantirn ae programs , increased volume on the sof clss program , partially offset by lower volume on longbow fire control radar and other programs . the increase for tactical missile programs was primarily attributable to increased deliveries on jassm and other programs , partially offset by fewer deliveries on the guided multiple launch rocket system and javelin programs. .
