What Are the Different Types of Army Career Opportunities?

The United States Army is a component of the United States Armed Forces and is primarily responsible for operations on land. It was formed on June 14, 1775. In fiscal 2017, it is expected to have 460,000 active duty personnel, 335,000 US National Guard (ARGN), and 195,000 US Army Reserve (USAR). GI was another name for the US Army during World War II . At present, the ground armed forces are the second largest in the world and the first in overall combat effectiveness. ^[1]

The United States Army's predecessor was the colonial militia. Its history can also be called two "Army", one is the Regular Army composed of professional personnel, and the civilian army is composed of various personnel ), Which includes militia, National Guard, organized reserve and recruits ^[2]

U.S. Army ranks are divided into officer ranks and soldier ranks ^[7-10]

Level and order

Although the current U.S. Army is composed almost entirely of volunteers, the U.S. Army can issue mobilization orders in the face of world wars such as invasion by foreign enemies. The levels and sequence of mobilization are as follows:

US Army Organizational Change

According to the "National Defense Act" promulgated by the US Congress on June 4, 1920, the U.S. Army consists of three main components: the regular Army, the National Guard, and the Army Reserve.

The regular Army and Army National Guard, consisting of conscripted reserve officers, volunteers, and compulsory soldiers, became the main force in the United States Army. The term of conscription is defined as "duration" of more than 6 months.

According to the National Defense Law of June 4, 1920, the regular military post is 288,000. According to this law, the whole country is divided into 9 military regions under the jurisdiction of 3 group army headquarters. Each military area includes 1 regular army division, 2 national guard divisions, and 3 first-class reserve divisions. But because the United States in the 1920s was not only immersed in the dream of "the war has ended forever", but also the government was more enthusiastic about the economy and only supported the "Defense Law" verbally without seeing action, so this goal was not achieved. . Despite the encouraging prospects of the 1920 National Defense Act, the period between 1920 and 1930, the readiness of the US Army was worse than at any time in history.

6. The 4th Infantry Division of the United States , nicknamed " Ivy " , belongs to the 3rd Army and is stationed in Fort Hood, the United States.

The division is mainly composed of tanks and mechanized infantry, and includes a combined force with air assault forces. It has fast mechanical power, powerful fire and assault forces, and armor protection. It is a standby force for the US military to support global military operations.

At the end of 2000, after the 4th Infantry Division was changed to a digital division, its establishment was adjusted. First, the number of personnel was reduced from more than 18,000 to more than 15,000. With the reduction of weapons and equipment (the armored battalion tanks and the infantry battalion infantry fighting vehicles were reduced from 58 to 44), the overall size of the division was 25% smaller than the original. Secondly, the engineering brigade was abolished, and its engineering battalion was incorporated into each armored brigade and aircraft infantry brigade, and the division-level brigade-level unit was reduced from 7 to 6. The division artillery cancelled the target search company, and the multi-barrel rocket launcher was expanded to a multi-barrel rocket launcher battalion, and the remaining units remained unchanged.

In addition to the establishment of this adjustment, the weapons and equipment have also been changed. The M1A2 main battle tank and M2A3 infantry fighting vehicle replaced the M1A1 main battle tank and M2A2 infantry fighting vehicle. The AH-64A Apache was replaced by the AH-64D Longbow Apache. In addition, it is also equipped with new air defense radars, surface-to-air missiles, and drones. The new digital 4th Infantry Division has fewer weapons and equipment, but is more advanced and more powerful. The multi-barrel rocket launcher was expanded into a multi-barrel rocket launcher battalion, which strengthened the long-range firepower of the division. Each brigade has increased reconnaissance units and improved battlefield situational awareness. Each brigade also has its own engineering battalion, which greatly strengthens its engineering support capabilities and enhances its independent combat capabilities. In March 2003, when the Iraq war broke out, the 4th Infantry Division had a great opportunity to demonstrate the great power of the Digital Division. But what is surprising is that the 4th Infantry Division, originally responsible for the main offensive task in northern Iraq, was unable to carry out the attack because Turkey refused to use the ground forces of the U.S. Army, and had to make a large circle from the Red Sea to the Persian Gulf to join the southern battlefield. As a result, when the still bloated digital division made a long journey and slowly rushed to the theater, the main war in Iraq had ended. The digitized division lost its opportunity to demonstrate its power, forcing senior US military personnel to recognize its shortcomings and prepare to adapt it again.
