Hi aspirant,

To get ACC(Army Cadet College) army entry candidate must be age between 20 to 27. Also must be cleared 10+2 from recognized board or university. There is no mention about civilian ir military background. So yes if you are civilian background and age between 20 to 27 and cleared 19+2 then yes you can take ACC army entry.

Hope this is helpful to clear your dilemma.
