How did World War 2 affect soldiers?

World War 2 was one of the largest and most devastating conflicts in human history. Over 60 million people died as a result of the war from 1939 to 1945. Soldiers who fought in World War 2 faced unimaginable horrors on the battlefield and were deeply affected by their experiences during and after the war. In this article, we will explore some of the ways that World War 2 impacted the lives of soldiers who served.

Physical Effects

Many soldiers suffered serious physical injuries and trauma during World War 2. The brutality of the fighting meant that horrific wounds from gunshots, shrapnel, burns, and more were common. Soldiers fighting on the frontlines faced the constant threat of death or dismemberment. Even those not directly injured in battle were still susceptible to physical ailments like trench foot from living in cold, wet conditions. In total, over 21 million soldiers were wounded during World War 2. Many of those who survived had permanent disabilities from amputations or other serious injuries. The intense psychological strain of combat also took a physical toll, leading to symptoms like fatigue, headaches, stomach issues, and more.

Mental Health Effects

In addition to physical wounds, World War 2 also profoundly impacted the mental health of soldiers. Living under the intense stress and trauma of war for extended periods of time took a major psychological toll. Soldiers had to endure horrific experiences like combat, witnessing death, deprivation, fear, and more. Many developed lasting mental health issues like post-traumatic stress disorder or PTSD from the trauma. PTSD was not formally recognized at the time, but symptoms included flashbacks, anxiety, insomnia, and disturbing memories of battle. The constant violence deeply shook soldiers’ faith in humanity, making it difficult to transition back to civilian life. Other common mental health effects included depression, anxiety, substance abuse, and suicide ideation. Mental health resources were very limited, so many struggled alone.

Disruption of Normal Life

For most soldiers, fighting in World War 2 completely disrupted the trajectory of their normal civilian lives. Young men were shipped off to war away from their homes, families, studies, and jobs. This interruption of their life plans and loss of years deeply impacted soldiers. Once the war ended, it was difficult for veterans to simply pick up where they had left off years before. Returning soldiers struggled to reconnect with estranged spouses and families. Finding employment was hugely challenging for veterans bearing both physical disabilities and psychological scars. The difficulties of readjusting contributed to mental health issues and homelessness for some veterans. Overall, the war derailed and dramatically altered what would have been the normal civilian lives of soldiers in its absence.

Loss of Comrades

One of the most painful impacts of World War 2 on soldiers was the traumatic loss of comrades and friends on the battlefield. Soldiers formed tight-knit bonds with their fellow troops while serving together under life-threatening conditions. When those friends were killed in brutal combat, it inflicted deep psychological wounds. Soldiers had to push through and keep fighting after losing people they had bonded with, shared stories with, and relied upon for survival. Experiencing so much death around them often led to survivors’ guilt for those who made it out alive. The memories of losing their comrades stayed with soldiers long after the war and was a source of lasting grief and pain.

Positive Bonds Between Soldiers

Despite the horrors, soldiers were also able to form positive bonds with each other during World War 2 that provided comfort. Soldiers formed intense friendships and connection while serving in units together for extended periods. They depended on each other for survival and shared perspectives that those on the homefront could not fully understand. Soldiers were able to laugh, exchange stories, talk about life back home, and more during breaks from combat. These bonds helped them cope with the trauma and gave them motivation to keep fighting. The shared experience of war connected veterans together for the rest of their lives. Veterans’ organizations helped preserve the camaraderie and provide support. These bonds between soldiers provided a small positive counter to the terror of war.

Wartime Romances

Wartime romances were another profound way that World War 2 affected soldiers’ lives. Young people thrown together by war sometimes fell in love and got married quickly, fearing they only had a short time together. Nearly 1 million American soldiers ended up marrying women from foreign countries like the UK, France, Italy and Germany where they were stationed. The war disrupted normal courtship rituals, leading to very rapid marriages. For some soldiers, these whirlwind romances and marriages left positive impacts and lasting relationships. Other wartime romances ended in heartbreak when the soldier was killed in action or failed to return home to their love. Either way, romantic bonds formed during the heightened emotions of wartime left indelible marks.

Growth and Maturation

Despite the hardships, many soldiers were able to grow and mature in positive ways through their World War 2 experiences. Though young, they gained resiliency and independence by navigating dangerous situations. Leadership, problem-solving, and quick-thinking skills were developed that transformed them from naïve youths. Coping with trauma led to increased mental toughness, emotional maturity, and perspective on what truly mattered in life. Soldiers became accustomed to living in the moment and not taking life for granted. These positive personal growths shaped them for decades after. However, growth was still balanced with the scars of war that never fully faded.

Changing Views on Warfare

World War 2 fundamentally shaped how an entire generation viewed warfare, patriotism, and the military. Wide-eyed young recruits often entered the war with romanticized notions of glory and adventure. The unrelenting horrors of real combat quickly stripped away this naivety. Soldiers realized the incompetence of leaders and pointlessness of much wartime decision-making. Patriotic views were challenged by the deaths of so many comrades. Veterans emerged deeply disillusioned with combat and distrustful of the military establishment. In the postwar years, they helped drive anti-war sentiments regarding conflicts like Vietnam. The sobering realities of World War 2 shaped a generation’s perspectives on warfare for the rest of their lives.

Post-War Life

After World War 2 ended, soldiers faced huge challenges transitioning back to civilian life. The difficulties of readjusting ranged from finding jobs and reconnecting with families to coping with physical and mental trauma. Veterans often felt alienated as civilians could not relate to the life-altering experiences of combat and death they had endured. PTSD was very poorly understood at the time, leaving many veterans to suffer alone. Substance abuse, homelessness, and suicide rates ran high among veterans struggling to adapt. Support networks and mental health understanding were minimal. Building a career or getting an education was delayed by years of wartime service for most young men. Despite these challenges, many veterans found ways to successfully integrate back into society and lead productive postwar lives. But the scars of war never completely faded even decades later.

Lasting Impact on Families

Beyond just the soldiers themselves, World War 2 also profoundly shaped the families they left behind. Nearly 400,000 American soldiers died in the war, leaving grieving parents, siblings, spouses, and children back home. Even those who returned physically and mentally scarred burdened their families. Traumatized veterans struggling with PTSD, alcoholism, or disability impacted marital relationships and the well-being of children. Many soldier families remember the war as a time of great uncertainty, fear, and sorrow as they waited anxiously for any news while their loved ones were away. The economic impacts of the war and absence of fathers also took a toll. World War 2 directly and indirectly shaped millions of military families on the homefront for generations.

Changing Demographics

World War 2 had sweeping impacts on wider society including demographic shifts. With so many young men shipped overseas, gender roles and norms began changing on the homefront out of necessity. As women took over factory jobs and other wartime industries, independence and empowerment grew. African Americans and other minorities also saw shifts as they fought for civil rights while risking their lives for their country. Immigration to the U.S. increased in the postwar years, bringing new diversity of language, culture, and ideas. The baby boom generation was born as soldiers returned home and started families. Each of these demographic shifts traced back to World War 2’s disruptive societal influence.

Technological Acceleration

World War 2 drove accelerated innovation and technological change that impacted society as a whole. Wartime necessities spurred breakthroughs like radar, jet engines, and electronic computers that found civilian uses postwar. Advances in transportation, manufacturing, medicine, and more could be traced to wartime origins. Penicillin was mass produced and saved soldiers, later transforming public health. Nuclear weapons were born from the war and fundamentally shifted geopolitics. The technological ripples of World War 2 continued long after peace, shaping the modern world’s development across many fronts. Soldiers witnessed this rapid innovation firsthand, sometimes using untested new tools in battle.


World War 2 irrevocably shaped the lives of soldiers who served and their wider families. The physical brutality, mental trauma, loss of comrades, and interrupted life plans scarred a generation of troops. But bonds between soldiers, personal growth, and societal shifts also emerged. Physical and emotional wounds lasted lifetimes for many veterans. However, support networks eventually developed to help veterans cope and honor their sacrifices. World War 2’s complex effects reveal both the darkest and most uplifting sides of human nature. The scale and intensity of worldwide conflict impacted individual lives as much as the course of history.
