San Diego

Welcome to week four of Marine Corps boot camp. Your recruit has had a busy and challenging few weeks, but they’re well on their way to earning the title of Marine. Let’s get into what they’re doing this week.

Training Week Four Intel

At MCRD San Diego, week four of boot camp marks the beginning of Phase II of training.

The major focus of the week is swim week 🏊🏼‍♂️, which is one of the most difficult parts of training but is required for graduation. The Marine Corps is traditionally known as the world’s premier amphibious assault force. Marines around the world constantly find themselves deployed to sea or traveling via ship or small craft at some point in their careers. This fact is why the Marine Corps is so invested in ensuring that every one of their men and women are proficiently trained in water survival prior to joining their parent units. During swim week, they’ll have to leap into deep water, tread in it, use issued equipment to stay afloat, and figure out how to shed heavy gear that could cause them to be pulled under water.

In addition to swimming, land-based physical training is also a major part of week four. Your recruit will participate in another pugil stick battle, and will undergo their first Physical Fitness Test (PFT). The Marine Corps uses physical fitness as a means of preparing Marines to withstand the rigors of combat. The PFT measures a recruit’s core stability, strength, and endurance while reducing risk of injury. It includes 3 parts: pull-ups or push-ups, crunches or plank pose, and a 3-mile timed run. We’re sure that they’ll do a great job!

Last, your recruit will take part in an academic review. This review will cover a wide range of topics, including Marine Corps customs and courtesies, first aid, military history, Marine Corps uniforms, policy and organization, and leadership, to name a few.

In your letter 💌 to your recruit this week, be sure to wish them luck on the PFT, and ask them about their time in the pool during swim week 🏊‍♀️

By the end of the week your recruit will have completed Phase I of boot camp 🏅

I’ll be back next week to kick off Phase II.

Semper Fidelis,
Sgt. Maj. (ret.) Paul Davis
