Brain injuries, especially in the form of TBI, are considered to be one of the worst and most common types of injuries received by service members in combat. Asymmetric warfare, for instance, involves the use of explosive devices, IEDs, in which there has been a consequent rise in cases of soldiers with brain injuries. Such injuries may cause some amount of disability, with cognitive, emotional, and physical effects that tend to be severe and reduce the quality of life in veterans. Because the problem of brain injuries resulting from combat is so severe, there is a need for research in the following areas:

· The effects of combat-brain injuries.

· The antecedents of the injuries.

· The efficiency of the various approaches that are used to tackle it.

The studies in this area should continue for the benefit of the lives of military personnel and for the formulation of policies on training, armor, and medical treatment of such personnel (O’Keeffe et al., 2020). Moreover, awareness of the long-term effects of fighting pursuits on the brain may be helpful in the efforts to design more appropriate and effective degrees of rehabilitation for injured persons (Maas et al., 2022). The purpose of this research proposal is to determine the characteristics of brain injuries because of combat and to discover factors that may affect the severity and the aftermath of the injury.

Research Question

The central research question for this study is: What are some of the variables that are likely to lead to increased severity of the head and brain injuries that happen in combat, and how do these factors affect the future psychological and mental health of individuals who are in the military?

This research question would be appropriate to fill gaps in knowledge in the specific areas as to which aspects cause increased brain injuries in a warfare context and what the effects of these brain injuries would be on recovery. By considering these factors, the study will contribute to understanding how the effects of brain injuries could be reduced and how the quality of life of the affected could be enhanced.

Hypotheses

The study will test the following hypotheses: The study will test the following assumptions:

Hypothesis: At the micro level of the experience of warfare, the multiple concussive incidents during a fight bring about more severe traumatic injuries to the brain and significantly impair the individual cognitive and psychological well-being.

Null Hypothesis: There is no correlation between the number of reported battle concussions and the degree of brain trauma, as well as its effect on post-ad apostasy neuropsychological and emotional sequelae.

These hypotheses will serve as the framework for the research by giving a direct focus on concussive events, the severity of the brain injury, and the outcomes and extent of recovery of the victims involved.

Variables

The study will focus on the following variables:

Independent Variable: Incident reports of Military personnel Involved in combat activities and the likelihood of having suffered a concussion. This variable will be measured by how often the participant in the study was involved in direct fire or explosion combat, where they could have suffered from concussion.

Dependent Variables: The intensity of observed brain damage, evaluated based on medical history and neuropsychological tests;- long-term cognitive effects, diagnosed with specific neuropsychological tests, common among TBI patients;- self-estimated emotional state, including the levels of depression and anxiety and PTSD.

Control Variables: Age and gender, rank, and Years of service in the military. These variables will be eliminated to minimize their influences on the results generated so that the impact given by the independent variable is clear and without extraneous interference.

Participants

Participants for the study will be selected irrespective of tribal, ethnic, or community origin but will have to fulfill the following criteria: The participant should be military personnel; Should have a history of exposure to combat; Should have a documented history of brain injuries. The target population will be people from different branches of the military to ensure that they will be diverse in terms of ranking, gender, and years of service. The inclusion criteria for participants will be: Soldiers who have gone to war and suffered from TBI, depending on the medical records.

Participants in the study who are willing to abide by the procedures and volunteer for the study after being given a clear understanding of the procedures and consequences to expect from the study.

Certain conditions will be considered exclusion criteria, including neurological conditions that existed prior to the combat. Moreover, those patients who, due to certain mental conditions, cannot give informed consent to participate will also be excluded.

Sampling Method

In this study, the method that will be adopted to recruit the subject is the stratified random sampling technique so that the sample taken is as diverse as possible about the entire military population. The subjects chosen will be divided into rank, gender, and branch of service, and an equal number of subjects will be selected from each category (Brett et al., 2022). This approach will ensure that the results are applied to all military personnel.

The target sample size will be 100 participants, with 25 selected from each of the four major branches of the military. Specifically, the Plat has been created for the Army, Navy, Air Force, and Marine Corps. This sample size is from prior studies that have found these numbers adequate to find meaningful impacts for subjects with conditions related to the brain, such as those found in military groups. Recruitment will be done in cooperation with army healthcare institutions and veterans’ associations so that possible participants can participate in the research.

Conclusion

It is possible, to sum up this research proposal as the investigation of the severity factors of combat brain injuries and the consequences that affect soldiers’ further cognitive and psychological processes. Due to its emphasis on the connection between concussive events and the severity of brain injury, this study can provide beneficial findings to the field of military medicine and guide future interventionists to enhance the health of soldiers. By following the right approach and a good sample of the population, this study will form an excellent basis to combat issues related to brain injuries resulting from fighting.
