If you are a beginner, I recommend studying just the required liaisons and maybe the forbidden liaison sections, as these are the essentials. 1  If you're more advanced, study all three sections. It may be boring, but your pronunciation and ability to communicate at different levels of formality will improve dramatically.
The United States Navy claims 13 October 1775 as the date of its official establishment, when the Second Continental Congress passed a resolution creating the Continental Navy. With the end of the American Revolutionary War, the Continental Navy was disbanded.
The U.S. Army was founded on 14 June 1775, when the Continental Congress authorized enlistment of riflemen to serve the United Colonies for one year. The 14 June date is when Congress adopted the American continental army after reaching a consensus position in The Committee of the Whole. This procedure and the desire for secrecy account for the sparseness of the official journal entries for the day.
