I was not questioning your decision to leave the military which is a personal one and it must be a very difficult place to be at the moment particularly for those with families. I was suggesting that moving on from any job is something that needs to be planned - particularly if you have a family needing to be fed. I am sure that you gave it lots of thought and have a plan B.
I was just suggesting to others who may be considering leaving and are reading this that you need to be sending out CV's and talking with people months before you leave and have a good idea of the job market before you make the move. As you have discovered things are not good at the moment.
As others have said though it is a cyclical industry and just 12 months ago you would have had little problem in getting a job. Give it another 12 months and the situation may be the same. Good luck.
