TO&E drawing, Japanese Infantry Company, IJA infantry regiment Type 2, 1945

On 28 February 1945 Imperial Japanese Army introduced new TO&Es for the divisions to be formed for the Homeland defense. 

Type 2 infantry regiments were to be formed for the "Mobile Striking Divisions" (機動打撃師団), intended to counter-attack US forces, that landed on the Japanese Islands (Type 1 infantry regiments were for the "Coastal Deployment Divisions" (沿岸配備師団) to defend the coastline proper).

Besides increased number of grenade dischargers, company and platoon organization of the new company was roughly similar to the standard infantry company organization from 1940.

But squad organization was a bit different. In 1945, the Infantry Training Inspectorate published "Infantry Combat Training", which officially introduced the so-called "group tactics". Now rifle squads were to be made up of 4, and grenade discharger squads - of 3 groups with its own designated leaders. Also grenade discharger groups now could be attached to the rifle squads, which was not allowed before (probably that was the reason for the increase of the number of grenade discharger teams in the squad).
