Yea it's weird, I understand each individual word he types, but arranged in the order they are leaves me baffled. I feel like an archeologist looking at hieroglyphics: "ok I've got snake, a bird and river. I know those. But what does it mean all together?" And then I look at the post he's replying to and all my theories explode.
Yes, you can apply for ANG/Reserves and AD simultaneously. My AD recruiter told me it would be a "conflict of interest," but that's a load of BS. From my understanding, you can continue to apply to guard units all the way up until OTS. You've made no commitment to anyone thus far.
Self-inflicted wound by your unit. I've been a UDM before...you only have to be current the day you set foot in the AOR. The only exception is Information Assurance, because the forward location will yank your network access if that one expires.
