Military Education for Starters
We strongly encourage military and civilians alike to grow deeper in their knowledge of human nature, military conflict, military strategy & tactics, morality & ethics, and why peace should be valued.
For those who have never served in the military, have limited exposure to the military lifestyle, have only recently begun their military service, or will be starting their military service soon, the following will introduce you to how you can self-educate and prepare yourself for interacting with those who practice arms.
In general, the best way to educate yourself militarily is to read. If you're at the beginning of your journey, several of the below lists will have books posted from most elementary (lower ranks) to more advanced (higher/officer ranks). The books listed will introduce various military topics, conflicts, histories, and stories, but are by no means comprehensive lists.
US MARINE CORPS RELATED LISTS
Most Marines are familiar with the Commandan't reading list. It contains recommended reading for Marines of all grades. The reading list changes from time to time. It's always worth revisiting.
Visit the Commandan't Reading List For Civilians here. See navigation pane on left-hand side for a lists related to military levels.
OTHER MILITARY READING LISTS
So as not to reinvent the wheel, this is just a reposting of a list-of-lists already compiled by USMC. You will find secitons pertinent to Army, USMC, Navy, Air Force, & Coast Guard. Additionally, there is an annotated list put out by the Australian Army that provides summaries of various books so that it's easier to determine what might be of interest for your specific situation/tastes.
