In warfare , a theater or theatre is an area in which important military events occur or are in progress. A theater can include the entirety of the airspace, land, and sea area that is—or that may potentially become—involved in war operations.

104-404: A Japanese reinforcement group belatedly arrived on the scene and, in retiring, sank USS Strong with a long-range torpedo shot. After another trip to Rice Anchorage with supplies and ammunition, Schley sailed from Espiritu Santo on 1 August for overhaul at Mare Island . Schley left the west coast for Pearl Harbor on 7 October, but engine repairs at Pearl Harbor took most of the rest of

On 5 July, she landed a second group of troops at Rice Anchorage , New Georgia. During this operation,
312-474: A retreat is taking place, or that upon the one an army is acting defensively, whilst an offensive is being carried on upon the other. Such a clearly defined idea as this is not capable of universal application; it is here used merely to indicate the line of distinction. Theater of operations (TO) is a sub-area within a theater of war. The boundary of a TO is defined by the commander who is orchestrating or providing support for specific combat operations within
364-517: A theater. The Russian-language term for a military "theater" is театр военных действий , teatr voennykh deistvii (literally: "theater of military operations"), abbreviated ТВД , TVD .

520-781: The 1st Ukrainian Front (1943–1945, which fought in Ukraine, Poland, Germany, and Czechoslovakia), and the Northern Front (Soviet Union) (June to August 1941). In peacetime, lacking the urgencies of a strategic direction, fronts were transformed into military regions (districts) responsible for an assigned section of operations. In 1986 the U.S. Department of Defense's Soviet Military Power identified ten continental and four oceanic TVDs, however, most being merely geographical areas without forces or headquarters: North American, South American, African, Australian, Antarctic, Arctic Ocean, Atlantic, Indian Ocean, and Pacific. Four others -
572-1039: The Asiatic Squadron and the Pacific Squadron were combined. In 1910, the ships of the First Squadron were organized back into a separate Asiatic Fleet .

An official military encyclopedia published after the Fall of the Soviet Union stated, said Harrison, that the Soviet Pacific Fleet , an air army , and an air defence corps were also operationally subordinated to the new formation; and that the high command "coordinated" with the armies of Vietnam, Laos, Cambodia, and Mongolia. The headquarters
780-485: The Long Beach Naval Shipyard . Light cruisers, destroyers and submarines were stationed at San Diego . During the summer of 1940, as part of the U.S. response to Japanese expansionism , the fleet was instructed to take an "advanced" position at Pearl Harbor , Hawaii. Admiral James O.

1248-576: The Japanese Combined Fleet carried out the attack on Pearl Harbor, drawing the United States into World War II in the Pacific. The Pacific Fleet's Battle Line took the brunt of the attack, with two battleships destroyed, two salvageable but requiring lengthy reconstruction, and four more lightly to moderately damaged, forcing the U.S. Navy to rely primarily on aircraft carriers and submarines for many months afterward. Subsequently, Pacific Fleet engagements during World War II included

1456-628: The TO. Theater of operations is divided into strategic directions or military regions depending on whether it is a war or peacetime. Unified combatant commands of the Department of Defense (United States) have responsibility for military activities (combat and non-combat) within their area of responsibility . The Soviet and Russian Armed Forces classify a large geographic subdivision—such as continental geographic territories with their bordering maritime areas, islands, adjacent coasts and airspace—as
1508-553: The U.S. Pacific Fleet's surface ships were to be reorganized into six core battle groups and eight destroyer squadrons. Permanent core battle groups were to include a battle group commander, aircraft carrier, carrier air wing and at least two cruisers.

2132-421: The rest of the space embraced in the war. Such a portion is not a mere piece of the whole, but a small whole complete in itself; and consequently it is more or less in such a condition that changes which take place at other points in the seat of war have only an indirect and no direct influence upon it. To give an adequate idea of this, we may suppose that on this portion an advance is made, whilst in another quarter
