Military powers, treaties; appointments and temporary appointments

Congress has the power to declare war, raise and fund the military, and regulate its organization and conduct. The president, as commander-in-chief, has the authority to command and control the military forces, make tactical decisions, and deploy troops. However, decisions to commit troops to war and engage in combat are shared powers between the president and Congress.
Military powers of Congress include the power to declare war; appropriate money to equip the military and pay for new weapons; funds to maintain the military force must be approved every year; restrictions placed on the military power of the executive, like the War Powers Act; make rules governing land and naval forces; during times of war or domestic crisis, the Congress may grant special military powers to the President.
The Gulf of Tonkin Resolution in 1964 gave U.S. President Johnson any military force necessary to protect U.S. interests. The "War Powers Resolution" in 1973, which over-rode President Nixon's veto, restricted the President's power, without "Congressional Approval." The WPR was brought about by President Nixon's ground campaigns in Cambodia & Laos in 1970 and 1971, respectively.
The position of Commander in Chief, belongs to the US President. The president has the overall ability to make military appointments and to take military action with the advice and consent of the US Congress. Without Congressional support, military actions by the president, may not be funded by Congress. In addition, as commander in chief, war policies are proposed and under the war powers act, the president may take immediate military actions in an emergency.
