When you go to a lawyer and have a situation where all you need to do is some administrative routine to address your issue, the lawyer, not being able to litigate and therefore collect huge fees for his billable hours, will tell you that there is nothing that can be done to redress the wrong you have suffered.
A military commander is employed to develop winning strategies for winning conflicts/engagements/delivering the results his country is seeking: it is in their interest to continue engagement for this is the 'thrill' of the job. This is why people have an interest in joining the military, to protect and serve and fight and win. We must always be the one to win. Well sometimes we have to lose some to win something more.
