I don't think you could have chosen 3 more distinctly different goals.
1 - a senior military college (non SA) with a rigorous academic and regimental system, with no service obligation upon graduation;
2 - the oldest most recognized SA, a ground combat branch of the military where most graduates are headed for foreign soil, and the largest branch of the US military;
3 - the smallest SA, a sea service, the smallest branch of the military, with a multifunction maritime military/law enforcement/inspection/search&rescue mission, serving mainly the homeland waters of the US.
