Yes Taki's para book clearly ilustrates the Type 89 GD being used by the para's.
I see them in 1944 manual TOE, but there are none mentioned in Raiding Regiment TOE, you cited earlier:
The raiding regement had 816 men, armed with 455x 7.7mm Type 2 rifles, 769 x 8mm Type 94 pistoles, 27 x 7.7mm Type 99 LMG's 6x 7.7mm Type 92 HMGs, 4 x 7cm infentry guns 4 x 3.7cm Type 94 AT guns or 4 8cm Type 97 trench mortars.
Yet, I do not think they resigned from them later. Another inconsistency with text, and actual numbers
Type 97, yes 1200 not 400 as previously thought, and yes many many more units could of been equiped with it, I have sean film fottage of IJA paratrooers training with it, and it is listed in their TOE's.
I have seen this movie. Undoubtedly it IS 20mm AT Rifle, and it was transported by only 2 soldiers, not 4 (and they actually run with it). Now the question is:
Does IJN Paras also used them?
Generaly the IJA nd the IJN infentry squads should see higher AT values from wars start and they should increase over the course of the war, their value of 5 equates to 5 cm the game equilvent of a hand gernade, and the Type 99 AT mine (not realy a mine but an infentry anti tank device) was widely used buy both the IJA and the IJN at the squad leval, and capable of defeating 20 cm of armor, but often they were imployed in pairs to better efect- 30 cm.
I would say that Hard/Soft Attack is used before combat, so it represents range weapons. All mines/contact weapons should be included in AV, so if SNLF did not used AT Rifles, they should stay at 5 HA, at the war beginning.
One thing absent from SNLF units are Combate enginears, they did field Flamethrowers on many ocashions(Wake for example), and the SNLF paras did use them as well.
Flamethrower is not THAT complicated weapon, so it could be issued into infantry. Now, if it was common, that would in fact increase Hard Attack.
The Bushido thing was institutionalized, yes, in the ‘20s, but as an affirmative explanation and morale underpinning of pre-existing tactical proclivities.
We must remember, that Japan was an old nation, with BUSHIDO implemented earlier directly into SAMURAI code.
The first Meiji era census at the end of the 19th century counted 1,282,000 members of the "high samurai", allowed to ride a horse, and 492,000 members of the "low samurai", allowed to wear two swords but not to ride a horse, in a country of about 25 million.
Considering that HALF of old family Samurais were in appropriate age for serving in armed forces, that would leave only 1 million of them. And you have IJA army, IJN ships/forces, and air forces to fill.
Yes, there were reforms, but I do not think there was some kind of direct indoctrination into soldiers, especially not in that short period. Either you were from Samurai family, or you will still be this poor Ashigaru whos only job is to follow orders, and die for your Daimyo. I would say conscript Japan soldier, was still simple conscript.
Have a look at this web site : very well informed about IJA & IJN organisation, at all level (divisional, regimental, battalion, companies, squad...)
That is my main source. There is clear, that SNLF squad have 2 LMGs there. But here you have same manual, but with clearer chapters, and with all pictures.
