Once the initial excitement of returning home wears off, getting back into the family routine after deployment can often be difficult. Teenagers, who already have a lot of changes to worry about, can sometimes have a difficult time accepting the return of a family member from deployment. As the returning parent, you can do several things to help ease the transition back home:
- Let your teen know that you are sad to have missed important events in his or her life.
- Ask questions about what is going on in his or her life. Make an effort to get to know his or her friends.
- Finally, be sure to listen when he or she tells you about his or her feelings.
Taking these steps will allow your teen to open up to you and eventually will strengthen your relationship. For more tips, visit Real Warriors.
The Department of Defense (DoD) Combat Feeding Program (CFP) is responsible for all of the combat rations that feed service members and for the research, development, engineering, integration, and technical support of those rations. Their mission is to ensure that United States Warfighters are the best-fed in the world. It’s important that any new combat ration developed is fueled by the wants and needs of Warfighters themselves; they even field-test new rations to make sure that their requirements are being met. Items that pass their standards are then incorporated into ration menus so that they have a variety of nutritional meals to choose from.
The Meal, Ready to Eat™ (MRE™) is used by all military services to feed Warfighters during operations where food service facilities are not available. MREs are essential to military subsistence; they’re intended to provide a Warfighter’s sole sustenance for up to 21 days of deployment (in accordance with AR 40-25) and are still nutritionally adequate for longer periods if necessary. MREs™ are shelf stable for 36 months at 80˚F.
The Unitized Group Ration – Heat & Serve™ (UGR-H&S™) is designed to feed 50 Warfighters per module and is the first group meal consumed in early deployment, as soon as field kitchens (without refrigeration capability) are available. All components of the ration are pre-cooked and shelf stable for 18 months at 80˚F.
The UGR-A™ is also designed to feed 50 Warfighters per module and consists of high-quality group meals. The UGR-A™ is the only military operational ration that contains frozen food components. It’s based on a build to-order assembly process that requires refrigerated/ frozen storage and a field kitchen for preparation.
The UGR-B™ is used primarily by the Marine Corps to provide high-quality group rations that don’t require refrigeration and are quick and easy to prepare.
The UGR-Express™ (UGR-E™) is designed to provide a complete, hot meal for 18 Warfighters in remote locations where group field feeding wouldn’t be possible otherwise. It’s a compact, self-contained, self-heating module that doesn’t require cooks or a field kitchen for preparation. With the simple pull of a tab, the food is heated in 30-45 minutes and is served in trays to Warfighters like a cook-prepared meal.
The First Strike Ration® (FSR™) is a compact, eat-on-the-move assault ration intended to be consumed during initial assault by forward-deployed Warfighters. The FSR™ is shelf stable for 24 months at 80˚F and provides a new capability in that it is 50% lighter, smaller, and easier to prepare when compared to the MRE™.
The Meal, Cold Weather™ (MCW™) and Food Packet, Long Range Patrol™ (LRP™), which contain freeze-dehydrated entrees, are designed to meet the nutritional and operational needs for extreme cold environments, special operations, and long-range reconnaissance missions. They are shelf stable for 36 months at 80˚F.
The Modular Operational Ration Enhancement™ (MORE™) is an enhancement pack designed to augment operational rations with additional calories and nutrients when Warfighters are operating in extreme environments such as high altitude in cold or hot weather.

There’s probably no other body region people work on so hard to get results than the abs. The common goal of sporting a “six-pack” is why abdominal equipment machines make up the largest part of the commercial fitness industry. People are constantly searching for the key to the washboard stomach they desire, whether it’s the newest fad piece of equipment or traditional bodyweight-driven exercises.
Unfortunately, many of these abdominal exercises provide little improvement to the target musculature and inadvertently place the lumbar spine in a position that could lead to lower back pain and injury. Just a few examples of hip-flexor-dominant exercises that can place the exerciser at risk are supine leg lifts, supine leg lifts with partner-assisted push down (a partner pushes down on the raised legs while the exerciser attempts to decelerate leg movement), hanging leg lifts, leg levers (lying supine while maintaining feet six inches off floor), and leg levers with unilateral or “scissor” kicks are.
To understand why these movements are both inefficient and contraindicated, it’s important to have a basic understanding of the abdominal anatomy. The rectus abdominis, the primary “six-pack” muscle responsible for the flexion that occurs during a curl-up, extends from the pelvis to the lower sternum. It is not involved in moving the legs. The hip flexors are responsible for the leg movements in the exercises mentioned above, while the rectus abdominis and associated muscles attempt to stabilize the spine Without adequate stabilization, the strong pull of the hip flexors leads to a marked anterior tilt of the pelvis. The abs are often unable to maintain stability, and the strong pull of the hip flexors causes the pelvis to tilt, creating an increased curvature in the lower back that compresses the lumbar area. Over time, this can lead to back pain and injury.
As a general rule of thumb, if you’re unable to maintain a stable spine position, or if you have a history of lower back pain or injury, these exercises should not be performed. There are other abdominal exercises that you can use to train more efficiently and more safely.
Even the most novice exerciser will be familiar with this common abdominal exercise: the bent-knee abdominal curl-up, or “crunch.” It has replaced the traditional sit-up as a staple in abdominal training due to its ability to recruit the abs without excessive hip-flexor activity. By varying hand placement—across the chest, behind the head, or extended overhead—the difficulty of the movement can be increased.
Crunches with a stability ball
A popular method to increase the difficulty of crunches is to perform them with a stability ball. Therapists have used stability ball training for years, and they are now becoming a common sight in gyms, as well. By reducing stability, the ball forces the exerciser to use his or her core-stabilizing muscles to maintain position, increasing the challenge to the abs. The result is a significantly greater amount of abdominal activity when compared with regular crunches.
A method of ab training not used often is the standing crunch, in which you flex and rotate your torso in various ways from a standing position. During the high to low “wood-chop,” for example, the rectus abdominis and oblique muscles are active during both the downward and upward phases. With rotation, emphasis is concentrated on the obliques. These exercises also have more “real-world” functional relevance, as they mimic everyday movements. In addition, various types of resistance—such as medicine balls, cables, resistance bands, and cords—can be used to make these exercises more difficult.
It’s important to be aware that many common abdominal exercises are not only ineffective but, more important, can place stress on the lower back. Try one of the safer alternatives above, focusing on correct form. The right abdominal training can benefit your trunk muscle strength and endurance, increase core stability, and improve functional movement—and can also start you on your way towards developing your “six-pack” abs.
Strong sibling relationships are tied to good mental and emotional states, and more. A study by the University of Southern California shows that siblings appear to be deeply affected when a brother or sister decides to enlist in the military. While research shows that people in war-zone environments experience many sources of stress, the same sources of stress can in fact help bring family members closer together. As the sibling to a service member, it is important not only to accept the decision your brother or sister has made, but also to provide support—because it truly helps!
A myriad of dietary supplements make their way to the market labeled as “healthy” for the public. However, many contain dangerous substances, including steroids, and consumers have no idea they are taking harmful substances. Supplement Safety Now, a public protection initiative, was founded by the U.S. Anti-Doping Agency to make sure over-the-counter supplements are safe for consumers. For more information, read more about this initiative.
Have you ever had one of those days that never seemed to go well, from the minute you heard the alarm clock go off? Maybe you didn’t have time for breakfast, forgot your laptop at home, lost your temper when someone cut you off on your way to work, replied to an e-mail in a way you really wished you hadn’t, ate poorly all day, couldn't concentrate at work, and then couldn't find the energy to go the gym?
Ask yourself how you slept the night before. One factor that can contribute to bad days is lack of sleep. Not getting enough sleep is all too common in the military and across the country—it’s often looked at as the price you pay to get ahead. Some sacrifice sleep for social activities at night—web surfing, e-mailing, watching TV, playing video games, or one more drink out with buddies—which further worsens the issue.
Bottom line: Not getting enough sleep is pervasive throughout all ranks and has major negative impact on your health, relationships, and career. The effects of sleep loss affect performance in much the same way that alcohol intoxication does. So coming to work deprived of sleep is rather like coming to work drunk. Your interactions with others and your job performance suffer—which has a huge impact on safety. Losing sleep isn’t sustainable for the long run.
But the damage doesn’t stop there. In fact, sleep loss has a ripple effect throughout virtually every aspect of health and wellness, including your physical, emotional, social, family, and spiritual well-being (see the five program components of Comprehensive Soldier Fitness here). It increases your risk of disease and harms your social relationships and possibly your professional reputation.
Sleep deprivation can be a byproduct of mission demands, of course. In the military, sleep loss is sometimes used on the battlefield as a weapon, wearing the enemy down through non-stop engagement. The problem is that this strategy affects our own Warfighters, too. Senior leaders are cautious in employing this tactic, and it’s used only for specific, organized, orchestrated periods of time, allowing for a full rest and recovery before massive errors occur that can cost lives.
Where many of us go wrong is thinking this type of sleep schedule is normal and maintaining it post-deployment. Most people aren’t able to tell when their state of mind—alertness, mood, concentration—has been compromised by lack of sleep until gross errors are made.
I believe sleep is the single most vital wellness function we do every single 24-hour period, and yet it requires no treadmills, no weights to be lifted, no personal trainers, and not even special clothes. It has dramatic implications for your entire body and sets you up for optimization everywhere else. Sleep is commonly overlooked at the doctor's office because physicians (including myself) don't understand exactly how it works, and in fact, there is no standardized medical test to see if you are getting enough sleep. But that’s no reason to ignore the health treasures afforded to those who get a great night's sleep on a regular basis.
On average, we spend 20-25 years of our lives sleeping, and five to seven of those are spent the critical dream periods known as "Rapid Eye Movement." REM periods occur at regular intervals throughout a night of good rest (when not impaired by alcohol, caffeine, or other drugs). Unfortunately, many of us look at this time as wasted, yet it can be some of the most glorious "unconscious" time to improve our health!
During REM periods, your brainwave patterns register signals much like those produced when you are awake and concentrating. During sleep you also secrete hormones that repair tissue and renew microscopic damages to cells and organs before they develop into bigger problems. In fact, you actually concentrate and focus for several hours throughout a good night's rest as you repair your body! Your brain, the center of all health, is exercising while you lie quietly in dreamland! When you destroy the quality of your REM sleep, the result is poor performance, inattention, obesity, hormonal imbalances, poor appetite, lack of normal growth, high blood pressure, poor interpersonal skills, no energy for the gym, possibly diabetes, and more.
Getting enough sleep means you are more likely to live longer, experience less disease, retain information better, perform better, and get more out of your workouts. You will be more patient with others, less demanding and prone to anger, and able to optimize all aspects of human performance, including your family relationships.

Carrying extra weight in the form of fat has many downsides: It not only impairs your self-image, but it also hinders your athletic performance, leads to disease, and contributes to the aging process. What’s the best way to lose that extra flab? While intense resistance and endurance training—such as lifting weights and running—will achieve great results, experts say that the best form of fat loss is fat prevention. Here are a few tips to help you maintain a healthy lifestyle and avoid fat accumulations:
- Find activities you enjoy, like swimming or running with a friend.
- Participate in community events that encourage exercise.
- Get outdoors with your children and pets.
Remember that it’s important to begin slowly and increase exercise gradually so that physical activity is an enjoyable experience. You can get more tips from this news release by the American College of Sports Medicine.
Distractions are a great way to help reduce stress, as they allow a child or teen to take his or her mind off of deployment—to a point. A great idea for parents is to provide plenty of opportunities for social activities (i.e., sports, clubs, etc.). Many of the sources of stress from a deployment have no ready solution, so distractions can be helpful. Providing events that families can partake in together (i.e., bowling, arts and crafts, etc.) are a great way to bring families together. Research shows that the most common forms of adolescent distractions are reading, drawing, playing computer games, listening to music, and playing with pets.
Salmon is commonly touted for its omega-3 fatty acids. HPRC recently received a question about what foods other than salmon are the best sources of omega-3 fatty acids. For a complete answer, including the recommended intakes from the American Heart Association, please see HPRC’s answer.
Many adverse events associated with dietary supplement use go unreported. HPRC has developed one page information resources on how to report adverse events. Warfighters and their families can follow the directions for reporting adverse events to MedWatch (FDA) and Natural Medicines Watch. In addition to these sites, Health care providers can follow step by step directions for reporting via AHLTA.
