New generation of soldiers

Example 1: There will be a group of 40 soldiers. These soldiers have been instructed to march as a group wherever they go. When it comes to actually doing it, maybe 5 intend on marching, 25 don't want to, and 10 don't care. Now why is it so hard for one of the 5 to convince the other 35 to do the right thing?

Example 2: The same group of soldiers. In the morning before PT, we get accountability. Now if we are running behind, the 35 often pressure the PG to step off without getting a for-sure confirmation that everyone that is supposed to be in formation, is indeed in formation while the 5 are still counting.

Example 3: I once had a roommate, much newer to the Army than I was. He loved to drink to get drunk, eat excessively, he failed pt tests, failed weight/tape multiple times over, had horrible personal hygiene, was a messy individual, never secured his wall locker, continually disrespected NCOs and had a real problem with integrity. The first time I had an issue, I had a talk with him. It was obvious what I said to him didn't work, so the next time we had an issue, I talked to my squad leader who talked to his squad leader. This also seemed to "go-one-ear-out-the-other". So I went to his PS, who made immediate changes and gave him "corrective training". This didn't go over so well in the barracks and the PNN as I began to get dirty looks on a daily basis. The thing that got me was I had to tell someone else of your deficiencies before anything would change and then instead of taking responsibility for said deficiencies, you push all blame on the "rat".

Now we all signed up for a change in lifestyle, why must one have to convince others to conform?
