Every little thing matters all the time. Check and re-check yourself and your buddy. If it is wrong correct it, if it is marginal it is not good enough.

Hold yourself and your Ranger Buddy to the highest standards.

Do things right and pay attention to detail so often that it becomes a habit (wearing eye-pro, muzzle awareness, not driving faster than you can see…).
Doing the right thing is habit forming and saves pain and grief in the long run.

Someone once told me Rangers learn through pain; I’d rather we learn from being taught the correct way of doing things, enforcing our own standards (on-the-spot corrections) and following our own SOPs.

Once the little things and basics are down cold, they become habits that you live by all the time whether in combat or training.
This allows you to move to higher levels of proficiency in combat skills.
