Weapons deactived???? (White Giant)

Hi all just a quick question, I have 23000 heavy artillery which are deactived and I can only get 4000 of them active, Is it because I've only 1 million people in my army and not people to man them, also my defence index was sitting at 160 but now is 40 and back to level 1, If I was to raise goverment salary's above corporate salary would that do the trick, many thanks lee

Yes if you want to keep your military active and have worker shortages keep you gov salaries 10 above your corp salaries.
