GENTEXT/REMARKS/1.  Whether operational or recreational, the Marine
Corps remains steadfast in its commitment to a culture of mitigating 
risk.  This especially holds true during the 101 Critical Days of 
Summer (CDS) which occurs Memorial Day weekend through Labor Day 
(24 May to 1 September 2025).  
2.  Historically during this period, the Marine Corps loses more 
Marines to preventable off-duty recreational mishaps than any other 
time of the year as leisure travel and outdoor high-risk activities 
surge.  
3.  Over the past 5 summers, 59 Marines died in off-duty 
recreational mishaps with private motor vehicles (26), motorcycles
(15), and water-related outings (9) being the leading activities.
4.  As encouraged in reference (a), personnel must properly prepare
themselves when planning for and conducting summertime activities 
with known elements of risk.  Understanding hazards and taking 
action to mitigate and manage risk is a personal endeavor.  
Accepting or tolerating unnecessary and uncalculated risk endangers
risk-takers, innocent bystanders, first responders, and those who
answer the call for help.  Equally important, preventable off-duty
mishaps have added consequences by needlessly contributing to strain
on our resources and unquestionable stress on our families, friends,
and co-workers.
5.  Off-duty risk mitigation training prior to commencement of the 
CDS period and during the permanent change of station onboarding 
process has proven to be an effective means for minimizing the 
likelihood of preventable off-duty mishaps. 
6.  In support of this cause and per reference (b), all Marines and
Sailors shall receive documented summer safety briefings prior to
each extended holiday liberty.  Recommended key topics include
private motor vehicle and motorcycle operation, water excursions, 
responsible alcohol consumption, heat illness and injury prevention, 
inclement weather conditions, barbecue and camp fires, fireworks, 
camping, trekking, and any other recreational off-duty activity that 
increases the probability of a mishap. 
7.  Commanders and leaders at all ranks have a profound impact on
our readiness by inspiring individual and unit risk mitigation 
measures and reinforcing established safety protocols.  I encourage
all leaders to be creative when conducting CDS training by choosing
a location that complements the significance of summertime safety and
its underlying message.  Both the Naval Safety Command 
(https://navalsafetycommand.navy.mil/Off-Duty/101-CDOS/) and your 
local installation safety office serve as great resources for summer 
safety products and information. 
8.  By cultivating a safety culture in which calculating and managing 
risk is part of the decision-making process, we enhance readiness 
and build strong relationships of trust through demonstrating a 
genuine concern for the welfare of our warfighting team.  Having the
courage to speak up and take action to break the cycle of events 
that leads to a preventable loss aligns with our warrior ethos and 
is a trait each of us must strive to exemplify.
9.  This summer, I encourage you to have fun with family and friends, 
while also keeping safety and risk management an integral part of 
your decision-making, on and off duty.  By working together, sharing 
knowledge, and adhering to established safety protocols, we can 
mitigate risks and ensure a safe and successful summer.

Director, Marine Corps Staff.//
