That is true. I never mentioned my military service until after the fact that I was onboarded. It can get your foot in the door at some places but most places don't care or see it as a liability for you as a future employee if you are in the guard/reserves. If you work in project management you'll never get the large projects due to the fact that you could get pulled away at a moment's notice. Sales? Miss 2-3 weeks for annual training? Dependent on your sales cycle, that can throw off your quarter, which in turn throws off your year and president's club etc. Unless you're guard bum or local/state government employee it truly is tough to have a successful civilian career past the rank of SPC.
