I was raised in the Church of Christ that is affiliated with Abilene Christian College and Harding College. They do view baptism as a sacrament and is a requirement for salvation. The Church of Christ baptizes in the name of the Father, Son, and Holy Spirit. The CoC does not believe in original sin, and you must reach the age of accountability before you can be baptized.
The other sacrament they observe is the “Lord’s Supper” or what we call the Eucharist. The Church of Christ does view partaking of the bread and wine as figurative. The wine is actually grape juice and the bread is unsalted crackers. Partaking of the Lords Supper is viewed as a requirement, and you are to be in grace to accept it.
The CoC believes that salvation is a grace and gift from God, however, unlike some protestants denominations, salvation can be lost if sin separates you from God and/or your life doesn’t bear fruit for the Lord.
The CoC is based very much on sola Scripture, and a literal interpretation of the bible. As someone mentioned already, if it is not stated in the NT, it is not done. The CoC abhors church organization; each congregation pretty much stands on its own with a group of elders and deacons making decisions.
The CoC comes close to viewing marriage as a sacrament. Unless they divorce due to adultery, members are considered to be living in sin if they divorce and remarry. it is a just reason for the congregation to dis-fellowship with a member. There is no such thing as annulment.
