George Santayana warned, “Those who cannot remember the past are condemned to repeat it.” Training provides an opportunity to learn and improve, but experience alone does not guarantee that its lessons will be retained.
Whether you attend a professional course or conduct a focused practice session, taking notes and writing an after-action report (AAR) helps preserve the details, decisions, problems, and discoveries that would otherwise fade. Training requires time, tuition, ammunition, equipment, transportation, and often lodging. Retaining and applying its lessons protects that investment.
Why Write an AAR?
An AAR does more than remind the writer what happened. It turns field notes into a usable record, helps fellow students retain their knowledge, and gives prospective students a clearer picture of a course and its requirements.
Instructors benefit as well. A thoughtful student account can reveal what the class actually learned, where students struggled, where they were insufficiently challenged, and how the instructor’s demeanor or teaching style affected the experience. An AAR is not merely a review; it is a tool for continual learning.
Record Preparation and Context
A useful AAR begins before the first drill. Record the expected weather, clothing, support equipment, protective gear, magazines, firearms, modifications, food, water, and other preparation details. Context determines whether an observation can become a transferable lesson.
If a holster component breaks but the report never identifies the make, model, or circumstances, readers learn very little. The same applies to equipment that was not brought. Forgotten sunscreen, insect repellent, rain gear, food, or water may appear trivial until those omissions interfere with learning. Small details often produce the most practical lessons.
Take Notes While Training
Good instructors encourage note-taking. Record drills, round counts, malfunctions, equipment failures, performance changes, corrections, and “light bulb” moments. Even an individual practice session benefits from a written record that can guide the next session.
Do not record only what happened. Capture what you were thinking. Did a mental mistake precede a performance problem? Did an instructor’s adjustment improve the result? Did another student offer a useful perspective? Humbling lessons, questions, surprises, and even humorous moments make the AAR more complete and relatable.
Keep a notebook accessible at the firing line when conditions permit. Ask for clarification when you do not understand how or why something works. Review your notes during breaks and again between training days while the details remain fresh.
Draft After You Decompress
After returning home, take time to decompress. Clean and organize the equipment, restore it to serviceable condition, and spend time with the family members who gave up part of their weekend so you could train.
Then return to the notes after a short interval. Read them several times and expand the points that need context. Contact fellow students or the instructor when a memory is unclear or another perspective would improve your understanding. Turn the raw notes into a narrative that explains what occurred, what you learned, and what you intend to do next.
Training without retention becomes wasteful over time. Learning builds on earlier experience. Preserving and sharing useful lessons allows others to benefit without repeating every step and misstep themselves.
Seek Feedback Without Surrendering Your Perspective
Send the draft to classmates and the instructor. Correct factual errors and consider whether their observations deserve inclusion. At the same time, the AAR should remain an honest account of your experience rather than a consensus document written by committee.
Once the report is accurate and complete, consider sharing it with a wider audience. A published AAR can help prospective students determine whether a class fits their needs, understand how to prepare, and recognize what responsible training requires.
AAR Template
This template is a starting point. Adapt it to the class, audience, and purpose of the report.
Class Title
Identify the training company and full course title.
Instructor
List the primary instructor and any assistant instructors.
Location and Date
Identify the venue, town, state, and training dates.
Equipment Details
Document firearms, relevant modifications, sights, triggers, lights, holsters, magazine pouches, magazines, footwear, eye and ear protection, weather gear, food, water, and other support items. Connect those details to what worked, failed, or should change.
Personal Experience
Explain the perspective you brought to the course. Identify relevant professional, training, competition, or armed-citizen experience without overstating it.
Preparation Drills
Record how you prepared. Note any drills or study used to establish the prerequisite skills before class.
Class Demographics
Describe the general experience level and composition of the class. Obtain permission before identifying other students by name or revealing personal information.
Training-Day Narrative
Organize each training day into useful periods such as morning and afternoon. Record the setup, safety brief, drills, instruction, progression, breaks, environmental conditions, and how your preparation affected performance.
Between Training Days
Note group discussions, equipment maintenance, lodging, meals, preparation for the next day, and any review or practice conducted overnight.
Class Debrief
Summarize the lessons, successes, problems, and questions discussed at the end of training. Include useful perspectives from other students while clearly distinguishing them from your own.
After Class
Describe equipment recovery and maintenance, follow-up discussions, changes you intend to make, and a plan for practicing or testing the lessons learned.
Turn Experience Into Continued Learning
A well-written AAR preserves more than a sequence of events. It records preparation, equipment, decisions, mistakes, corrections, and future work. That record helps the writer retain the value of training, assists prospective students, and gives classmates and instructors another perspective from which to learn.
The final product should answer three questions: What happened? What did it teach me? What will I do differently because of it?
