Two planes, what's the plan?

November 23, 2015, two U.S. Army pilots stationed in South Korea were killed in a helicopter crash while performing a routine training mission. November 24, 2015, four U.S. Army crew members stationed at Fort Hood, Texas were killed in a helicopter crash while performing a routine training mission. Six lives lost during these routine training missions within two days, both with unknown causes and left under investigation. If these missions are routine then what happened with both helicopters that cost the lives of six trained people? How does our government plan on preventing further losses from situations like these?
It begins with appointed military commanders and leaders who pave the way for soldiers to follow. These leaders hold a direct impact towards preventing injuries and casualties. Therefore, it is of the upmost importance for the government to appoint their best and most highly trained men and women. During routine missions, leaders are put into positions where they are managing risk as well as being in charge of preventing accidental hazards. Furthermore, to avert these mishaps, the government should ensure leaders are instilled with good tactical procedures in these places that increase safety risks. Although, it should be noted that knowing tactical procedures and execution of these procedures are two separate things. Commanders and leaders should be experienced in the field in order to train soldiers sufficiently. When dealing with military conflicts or even during routine missions, simply knowing what you should do is ineffective if you are unable act them out.
If the government and our Commander in Chief don't appoint leaders with experience and the right knowledge then there goes one major source in protecting those who serve for us.
