As a former instructor and member of 3-75, I think the standards will determine who should serve and who should not. The problem is that when enough people fail to meet the standards the standards get questioned. The question "Why is the minimum standard the standard?" is a very complex and difficult question to answer. If the answer is not objective and immediate the standard will be attacked. Case in point, part of the Combat Water Survival Test (CWST) was the "Ditch Equipment" event. The standard was for the subject to completely submerge and remove equipment and drop the weapon while submerged. Seems straight forward enough....until a grader gives a student a no-go because they elbow broke the plane of the water befor the equipment was off. While the student met the spirit of the event he violates the standard. That is when hard questions start getting asked.
