Ditto what @HelpfulTracks said. You'd be nominated by your troop committee, and the assistance you would be providing would be facilitating participation in OA by the youth in your troop. (See the "Adult Nomination Form" in the document that @Col. Flagg linked).
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
Most people focus either on a well regulated Militia or the right to bear arms not being infringed. What most people don;t think about is "being necessary to the security of a free State". This clause gives the reason why the second amendment even exists. It doesn't exist so that people can use guns to hunt. It doesn't exist so that people can have guns for self defense. (Though those are secondary benefits which are still important - they're just not the primary reasons).
It exists so that people will be armed to come to the defense of their state and country. The constitution presumes that the United States and the States within are free states. It does not presume that the United States and the States are totalitarian dictatorships. It certainly does not presume that when people have disagreements with their government that they can take up arms against that government (example - the Whisky Rebellion - President George Washington himself didn't hesitate to send the militia in to suppress and subdue armed and violent citizens that were threatening (and more) duly sworn representatives of the government there to make sure that a federal tax on domestic whisky was collected).
At the time the second amendment was created, the founding fathers were wary of having a standing professional army. They had just seen how "ordinary citizens" (mostly - they did have help from "professional" soldiers) had defeated the most powerful army on earth at the time. They knew that an armed citizenry was a powerful force that could be called upon to defend their government(s) from OUTSIDE forces. They did not expect that people would need to defend themselves from their own government. Yes, yes - we've all read the whole at times the tree of liberty needs to be refreshed by the blood of tyrants stuff but that was very much a political statement aimed at one particular tyrant.
Your right to keep and bear arms is meant to have an armed citizenry ready to come to the defense of the government (the State). We've allowed the creation of a professional military to defend us. In doing so, we have allowed ourselves to believe that we can leave the defense of our country to others while we go on with our lives. This has allowed folks to twist the meaning of the second amendment to one of being able to defend themselves against their own government, and get away with it. Those folks are deluding themselves in these modern times. When you have a government with a standing army that can manipulate a silent drone from a thousand miles away to drop an explosive device on your home, there is no effective gun defense against your own government.
ps - yes, the Illinois Militia had 2 pound grasshopper guns (cannon). Like every other state, the Governor/Legislature could call forth citizenry to form temporary militias - these were the armies of a state, the militia members were paid for their service while they were part of the militia, by the state. While many members of the militia brought their own rifles, the state also had their own armories that they could outfit their militia from. If a militia unit had 2 pound cannon with them, they were provided by the state armory - not brought by some random guy who happened to own a 2 pound cannon and just happened to be in the area that the state was recruiting people for militia service.
Abraham Lincoln was a member of two different militia units. He served as elected captain (elected by the members of his militia unit) for 30 days, then when that militia units term expired (after 30 days), re-enlisted and served as a private. His militia units were formed for one purpose only, to chase down the Sauk Indians refusing to give up their land that they felt was ceded to the US by people not authorized to do so. We know it better as the Blackhawk War.
I have been hearing about this program more often from parents. Is the government promoting its own youth program? It has more participants than Trail Life or Scouts Canada.
The Congressional Award is the United States Congress’ award for young Americans. It is non-partisan, voluntary, and non-competitive. The program is open to all youth regardless of ability, circumstance, or socioeconomic status. Participants earn Bronze, Silver, and Gold Certificates and Bronze, Silver, and Gold Medals. Each level involves setting goals in four program areas; Voluntary Public Service, Personal Development, Physical Fitness, and Expedition/Exploration. Earning the Award is a fun and interesting way to get more involved in something you already enjoy or something you’d like to try for the first time. You move at your own pace, on your own or with your friends. This is not an award for past accomplishments. Instead, you are honored for achieving your own challenging goals.
Regardless of your situation, you can earn The Congressional Award. The Congressional Award has no minimum grade point average requirements. It accommodates young people with special needs or disabilities who are willing to take the challenge.
