First off, great work at the <url> article. I'm just wondering why you changed the sentence back to "During this period, defense expenditures underwent exponential growth allowing an unprecedent level of weapon acquisitions and the rapid expansion of the <url>." from "During this period, defense expenditures underwent exponential growth allowing an unprecedent level of weapon acquisition and expansion of the <url>." The version I changed it to is more grammarically correct, don't you think?
