"Shellshock" was a term commonly used during World War I to describe the debilitating psychological effects of combat. However, over time, this term has become outdated and is now considered insensitive and harmful to veterans who suffer from post-traumatic stress disorder (PTSD). As such, new synonyms have been developed to describe this condition, such as combat stress reaction, battle fatigue, and post-traumatic stress disorder (PTSD). These new terms better reflect the nature of the condition and help to promote a more positive and supportive environment for veterans who are struggling with the psychological effects of combat. It's important that we continue to evolve our language so that we can better support and understand those who have served our country.
