Overview
Following victory in Europe , the organization of the U.S. Army rifle company received a rework as part of changes to T/O No. 7-17. At this time the rifle company consisted of 1 company headquarters, 1 weapons platoon, and 3 rifle platoons.
​
With the exception of minor equipment changes, the organization of the rifle platoon did not change substantially between 1942 and 1948. Minor changes came to the company headquarters (mainly in the inclusion of an RTO billet and the addition of more basic duty riflemen to be used as replacements). Although this is entirely speculation on my part, the increase in the number of basic duty riflemen from 17 to 21 in the company headquarters could have been in preparation for taking heavier casualties in future Pacific operations. In February 1944, the Bazooka rocket launchers once allocated to the weapons platoon headquarters were transferred to the company headquarters to be issued when needed. This was reversed in June 1945, and the company headquarter's spare weapons inventory was reduced to 6 M1918A2 BARs. In the field, these BARs would be allocated to the rifle platoons so as to increase the firepower from 1 BAR per squad to 2. The Marine Corps had realized by that point that 1-2 BARs was insufficient for their needs, and increased their allotment of BARs to 3 per squad. The Army had not done this officially until late in the Korean War (possibly because there was no break in combat great enough to implement a major T/O change like this), but additional BARs were unofficially allocated so as to increase the squads' firepower.
​
The largest change came to the weapons platoon. From 1940 to 1945 (prior to 1940 the weapons platoon did not exist in rifle companies), the weapons platoon consisted of a mortar section serving 3 60mm mortars and an LMG section serving 2 M1919A4/6 belt-fed machine guns. The 81mm mortars were battalion assets contained within the battalion weapons company. In the changes made in June 1945, a special weapons section and assault section were added to the weapons platoon. The special weapons section contained 3 M18 57mm recoilless rifles, while the assault section contained 6 Bazooka rocket launchers and 2 flamethrower technicians. The mortar section and LMG section retained their basic organization. An assistant platoon commander was added to aid in command and control, while 2 additional jeeps, trailers, and drivers were added for a grand total of 4 each to accommodate the increase in equipment.
​
At the rifle platoon level, the basic organization remained the same: 1 platoon headquarters and 3 rifle squads. The rifle squad was identical to the February 1944 change when assistant squad leaders were promoted to sergeants and squad leaders were promoted to staff sergeants. Save for these promotions, the basic organization was the same as that set in the July 1943 changes. Prior to this (as of 1942), the only major difference was instead of having 3 M7 grenade launchers spread across the assistant squad leader and 2 rifle grenadiers, the squad was allotted 1 M1 grenade launcher paired with an M1903 Springfield with a dedicated rifle grenadier. This was because the M7 grenade launcher that was paired with the M1 Garand had not yet been issued. Otherwise, the squad manpower and structure remained the same.
​
Based on testimony given at the 1946 Infantry Conference that weighed possible improvements to the rifle squad and other small units, rifle platoons typically did not do squad-level fire and maneuver. Although Able (scout/security), Baker (fires), and Charley (maneuver) teams had been identified in late war manuals on squad tactics, it was found that either because of lack of experience among infantry NCOs due to attrition or because of the operational environment, most maneuver was done at the platoon or company level. This means that at the lowest levels squads would maneuver with cover from other squads in the platoon, or entire platoons would maneuver while other platoons in the company cover. This was much different for the Marine Corps in the Pacific, who solidified their 3 fire team per squad set up and small unit tactics in the mid and late war. Thus, squad-level fire and maneuver and the comparative lack of firepower (only 1 BAR) were not seen as problems in 1946. Rather, the issue was seen to be command and control difficulties due to the large size of the squads. The dominant opinion was against the inclusion of subunits (e.g. fire teams) at the squad level. The Marines had rectified command and control issues by creating a fire team structure with 3 fire team leaders in total for the squad leaders to delegate to. The Army's solution was to decrease the size of the squad from 12 personnel to 9 personnel with no discernible fire teams so that the squad leader could control the entire squad with aid from an assistant squad leader. Further, the Bazookas and light machine guns that were allocated to the weapons platoons were also transferred to a rifle platoon-level weapons squad. The weapons platoon assault section and LMG section were then dissolved. These changes were implemented in April 1948 with T/O 7-17N.
