Firstly, it's essential to acknowledge that moral guilt is a natural and essential emotional response to wrongdoing. It serves as a catalyst for personal growth, self-reflection, and ultimately, redemption. Manipulating soldiers' perceptions of their actions could potentially suppress or avoid these necessary processes.

However, if we assume that the goal is to alleviate the suffering associated with moral guilt, there are some theoretical frameworks and interventions that might be worth exploring:

1. Cognitive reappraisal: This involves reframing one's perception of their actions from a moral to a more neutral or positive perspective. For instance, instead of viewing an airstrike as "killing innocent civilians," they might see it as "carrying out a necessary military operation to protect their comrades." This approach focuses on modifying the soldiers' thought patterns and emotional responses.

2. Moral disengagement: This concept, developed by Albert Bandura, refers to the tendency for individuals to disengage from the moral implications of their actions. By acknowledging that moral disengagement is a common phenomenon, it's possible to design interventions that help soldiers recognize the consequences of their actions without necessarily inducing guilt.

3. Social identity theory: This framework suggests that group membership and social norms can significantly influence an individual's behavior and attitudes. By emphasizing the importance of teamwork, camaraderie, and shared values among military personnel, one could potentially reduce moral guilt by reframing it within a broader context of collective responsibility.

4. Mindfulness-based interventions: Practicing mindfulness meditation and cultivating self-awareness might help soldiers develop a greater understanding of their emotions and thoughts, leading to increased empathy and a reduced sense of moral guilt.

To implement these approaches effectively, several considerations should be taken into account:

1. Contextual factors: The military environment is unique and can influence the effectiveness of any intervention. Factors such as cultural norms, leadership styles, and peer pressure must be considered when designing an intervention.

2. Individual differences: Soldiers' personalities, values, and life experiences will significantly impact their response to interventions. It's crucial to tailor approaches to individual needs and circumstances.

3. Ethical implications: Manipulating soldiers' perceptions of their actions raises concerns about the potential for moral license or groupthink. Interventions must prioritize honesty, transparency, and accountability to avoid exacerbating the problem.

4. Long-term consequences: While alleviating immediate suffering is important, it's essential to consider the long-term effects of manipulation on personal growth, self-reflection, and ultimate redemption.

In conclusion, while manipulating soldiers' perceptions of their actions might offer some relief from moral guilt in the short term, it's crucial to approach this issue with caution, considering the potential risks and ethical implications. A more effective strategy might involve a combination of cognitive reappraisal, moral disengagement, social identity theory, and mindfulness-based interventions, tailored to individual needs and circumstances, while prioritizing honesty, transparency, and accountability.
