You don't have 4 jack to spend... Only 3! Because of upkeep. I find more and more people neglecting to remember about their upkeep in their orders, like I'm just going to forget about it, too... It's simple. For every 5 units you've got (naval or land), you've got to spend 1 jack on upkeep.
My mistake! How about only 2 new military units then?
