In any major military operation this has been done by every president. The reason for this is the congressional power of the purse. The president will always need funding for any major military operation, therefore Congress still has the final say.
I would say not and the reason is that Congress has 535 members who often not even in Washington and can rarely make a quick decision about anything. Often events that need military intervention come to light suddenly and require quick action. Also an element of surprise or even secrecy is frequently needed and 535 people can not keep a secret.
The War Powers Resolution of 1973 was prompted by presidents sending troops without a formal declaration of war by Congress. Presidents had violated Congress' power over 100 times.
I dont know which party lead congress but these are the presidents. Truman was president when we started sending military aid to the French in 1950. Eisenhower & Kennedy were presidents as U.S. military advisors increased in number during the 1950's & early 1960's. Johnson was the president when the escalation in troops happened in 1965-1968. Nixon was president when the official cease-fire was signed in 1973. Ford was president when Saigon fell in 1975.
Five presidents played a part in the conflict. Eisenhower started sending in military advisers. Then Kennedy, Johnson, Nixon and finally Gerald Ford got the US out of it.
Presidents do not need the approval to send troops anywhere in the world. However, generally the president attempts to have a consensus with Congress when sending troops somewhere.

The War Powers Act gave the President some control over sending troops into battle. The President did not have any power to begin a conflict before this act; only Congress can declare war, but with the passage of this act, he is now allowed to send limited troops for a limited time. Congress shared a piece of their power with the President.
Eisenhower believed in sending troops, Kennedy did not.
