Fifth Division IJA
Posted: Sun Jun 12, 2011 11:29 am
This is possibly a unique formation. It is one of only two "semi-motorized" divisions in IJA,
and the only Class A Motorized Division formally. The best information about it, probably,
is in Tsujis more famous book, Japan's Greatest Victory, Britains Greatest Defeat. Col Tsuji
is a peculiar figure in history, much malaigned in the West, and because regarded as a
"war criminal" assumed to be a liar and unreliable source. He is much more complicated
than that - a true patriot and nationalist - eventually he headed a nationalist party in the Diet -
and, when ordered to do so, even became a US agent in the post war world! He was very
anti-Imperialistic, and believed in Asia for the Asiatics - so anyone who served the hated
Europeans or Americans was literally a traitor (which makes his later service very interesting:
in the post war world, many things changed - his first act was to join the KMT and one of his
lesser known books tells of his adventures with its Army - where he got along very well).
When the Cold War began, Japan became a real US ally - and his experience in SE Asia and
command of languages made him an invaluable asset to both - and he ALWAYS obeyed orders
from the Japanese Army. Anyway - to think he misrepresents things is to misunderstand why
he wrote his books. He has a point of view - but it is an ethical one from his own perspective.
He is, for example, a big fan of Churchill, and thinks he must really be a Zen thinker!
Anyway, Tsuji tells us the Fifth had TWO long weapons per line soldier - a rifle and a LMG.
These were mainly bicycle infantry, and they could carry more than walking troops. When they
came to a strong point, the troops would stop, dismount, select weapons and go tactical on foot.
Tsuji says they did not have to go back for the bikes - Malays would bring them forward - and
not steal the guns or other gear. But, even if you believe that, which I do, obviously no soldier
used both at the same time. In the tactics of the era, if an LMG is available, there is probably only
one per squad in useful service - so no TO&E should show the actual number of weapons of this type.
There are problems with the stock OB. Starting with - why does it have 1943 squads - in 1941?
Second, it appears the HMG squads assume a Japanese 13.2 mm HMG - based on US usage of HMG
to mean .50 cal. But a Japanese HMG is a 7.7 mm Type 99 (if not a 6.5 mm in a B Type unit).
Another problem is the formation is called a B type division - but it is a Class A division - and I see
NO stock formation called a Class A division at all (and if there are any, this formation isn't pointing
at one of them). Missing, entirely, is the 20 mm AT Rifle - and other weapons are somewhat
confused. In spite of that - one can see the OB really is related to the Fifth in important respects -
and many weapons are at least present in the right numbers for their type - even if not exactly the
right weapon. Other cases have the exact weapon in the wrong numbers, because this is NOT a regular
division in any sense.
The first problem is the infantry squads. It probably is incorrect to use 1943 squads in 1941. But in any case,
how do you represent them for a "semi-motorized division"? This unit has motorized logistics support regiments,
rather than draft, and it has the operational option of moving infantry on trucks rather than "marching" with
its bikes. The organization probably has 324 line infantry squads (9 per company, 36 per battalion) - but I represent
them as only 216 regular squads - and 108 motorized squads - to create the effect that motorized lift was available
when useful. Each of the companies has 2 organic HMG (before the special attachments for the invasion of Malaya)
and 2 AT rifles. There are 4 companies in 9 battalions, so that is 36 HMG and 36 ATR right there. Each battalion also
gets another 4 HMG - remember these should be Type 99 MMG as we would classify them - for another 36. Here it gets
muddy - there MIGHT be as many as 12 more AT rifles in the battalion gun company - which would be 36 more of them
as well. Regardless, each battalion gets a battalion gun company with 4 (rather than the more typical two) 70 mm
howitzers in two platoons - and in this case - likely two more platoons each with 6 AT rifles. This is class A organization,
designed by Yamashita for the not fully implemented mechanized army of the North, after returning from the Eastern
Front - having observed modern mobile units from German lines.
