Question: The Commander-in-Chief's Trophy is awarded after the Army-Navy Game, which is a game between which two parties?

<P0-S0>  The Black Knights (formerly the "Army Cadets" and "Army Black Knights") and Midshipmen each represent their service's oldest officer commissioning sources. <P0-S1>  As such, the game has come to embody the spirit of the interservice rivalry of the United States Armed Forces. <P0-S2>  The game marks the end of the college football regular season and the third and final game of the season's Commander-in-Chief's Trophy series, which also includes the Air Force Falcons of the United States Air Force Academy (USAFA) near Colorado Springs, Colorado. <P0-S3> The Army–Navy Game is an American college rivalry game in college football between the Army Black Knights of the United States Military Academy (USMA) at West Point, New York, and the Navy Midshipmen of the United States Naval Academy (USNA) at Annapolis, Maryland. <SEP> <P1-S0> The Commander-in-Chief's Trophy is awarded to each season's winner of the American college football triangular series among the teams of the U.S. Military Academy (Army Black Knights), the U.S. Naval Academy (Navy Midshipmen), and U.S. Air Force Academy (Air Force Falcons). <SEP> <P2-S0> In cryptography, a trusted third party (TTP) is an entity which facilitates interactions between two parties who both trust the third party; the Third Party reviews all critical transaction communications between the parties, based on the ease of creating fraudulent digital content. <P2-S1>  In TTP models, the relying parties use this trust to secure their own interactions. <P2-S2>  TTPs are common in any number of commercial transactions and in cryptographic digital transactions as well as cryptographic protocols, for example, a certificate authority (CA) would issue a digital identity certificate to one of the two parties in the next example. <P2-S3>  The CA then becomes the Trusted-Third-Party to that certificates issuance. <P2-S4>  Likewise transactions that need a third party recordation would also need a third-party repository service of some kind or another. <SEP> <P3-S0> A two-party system is a party system where two major political parties dominate the government. <P3-S1>  One of the two parties typically holds a majority in the legislature and is usually referred to as the "majority" or "governing party" while the other is the "minority" or "opposition party". <P3-S2>  Around the world, the term has different senses. <P3-S3>  For example, in the United States, Jamaica, and Malta, the sense of "two party system" describes an arrangement in which all or nearly all elected officials belong to one of the only two major parties, and third parties rarely win any seats in the legislature. <P3-S4>  In such arrangements, two-party systems are thought to result from various factors like winner takes all election rules. <P3-S5>  In such systems, while chances for third party candidates winning election to major national office are remote, it is possible for groups within the larger parties, or in opposition to one or both of them, to exert influence on the two major parties. <P3-S6>  In contrast, in the United Kingdom and Australia and in other parliamentary systems and elsewhere, the term "two-party system" is sometimes used to indicate an arrangement in which two major parties dominate elections but in which there are viable third parties which do win seats in the legislature, and in which the two major parties exert proportionately greater influence than their percentage of votes would suggest.
