In my mind, the point of a term policy is that you can guarantee specific coverage for a specified amount of time, regardless of your life changes. Think into the future, not just about your pending active duty status. (Stay safe btw)
My point is this, your health may change for the worse in the coming years, you and your wife very well may have children, buy a house etc... In a few years you will need more coverage than you do now, so buy it now, it will be cheaper...
buy enough coverage so that in a few years if you get hit by the beer truck it will pay off the house, put your kids through college and take care of your wife for the foreseeable future. If you have kids and you die, your wife will have her hands full and may not be able to work full time... Don't put her in the position to have to!
