As a SPC, what's the best way to separate myself from my peers?

Don't segregate yourself, if not influence the people within your sphere to be better.

Try to teach younger Joes, share your experience/knowledge and be an extension of your NCO support channel.

Lastly, ask your NCO what do you need from me as a soldier and a future leader to improve our teams/section/squad effectiveness.

It sounds like you are doing what you need to do. Step up when the opportunity presents itself, study your craft, pay particular attention to your equipment-weapons and vehicles. Know the TM’s inside and out. It is in the maintenance of your equipment where you can be most relevant at your grade. NCOs are always getting pulled to meetings and planning sessions. Become the one they can turn to who wants to lead and is technically proficient. I assure you there is something to learn. Do not get Cocky, nor overconfident. Thank you for your service.

1. Be more knowledgeable than decently- become an expert. 2. Lead when ever possible. 3.Get involved with your team/squad. 4. Help those having problems with a mission/assignment, etc.
