__ Presidents have used their role as Commander in Chief to take military action and to send troops out. This is an example of A. Formal Amendment B. Informal Amendment C. Reserved Powers D. Supremacy Clause

## Step 1<br />The question is asking us to identify the type of constitutional amendment that is exemplified by the president's use of their role as Commander in Chief to take military action and send troops out. <br /><br />## Step 2<br />The options provided are: Formal Amendment, Informal Amendment, Reserved Powers, and Supremacy Clause. <br /><br />## Step 3<br />A Formal Amendment is a change to the Constitution that is made through the formal amendment process, which involves a proposal by two-thirds of both houses of Congress and ratification by three-fourths of the states. <br /><br />## Step 4<br />An Informal Amendment, on the other hand, is a change to the Constitution that is made through interpretation by the courts or through the actions of the executive branch. <br /><br />## Step 5<br />Reserved Powers are powers that are not specifically granted to the federal government by the Constitution, but are instead reserved to the states. <br /><br />## Step 6<br />The Supremacy Clause is a clause in the Constitution that establishes the Constitution, federal laws, and treaties as the supreme law of the land, overriding any state laws that conflict with them. <br /><br />## Step 7<br />In this case, the president's use of their role as Commander in Chief to take military action and send troops out is an example of an Informal Amendment. This is because it is a change to the Constitution that is made through interpretation by the executive branch, rather than through the formal amendment process.
