Hello Dear,

OTA stands for Officers Training Academy. OTA is where ladies and gentlemen both are trained into officers but in IMA only gentlemen can be inducted for permanent commission.  After the completion of your Training in OTA you will be inducted into the armed forces as a lieutenant for maximum 15 yrs of service as Short service commission (SSC). Job nature is same for both the officer permanent commission or SSC. yes the officer from OTA also posted in the front area or battle field.

Good Luck
