Resilience programs (such as Expanded Operational Stress Control, or E-OSC) focus on improving overall health and well-being, including increasing the ability to withstand and recover from adversity. Toughness programs, including WT, focus on increasing performance on specific tasks (in this case, warfighting). Tough individuals are able to give their best-ever performance, even under high-pressure situations like combat and high-risk training. WT takes this further to ensure we are executing our warfighting skills ethically, demonstrating good character. Both resilience and toughness are needed for human optimization. Although there is some overlap, research shows individuals can be resilient, but not tough (and vice versa). Studies also show they are two different attributes which require unique training to develop them.
