Hello all,
Another round I must add, after eating some steamed rice and drinking some tea to meditate upon the "Do" of the tank, also known to the wide populace as the art of "Sensha-Do"... ahem, no, not really, just another bout of creating something and digging into numbers as usual, as per my passion which is getting stronger than actually wargaming the further time goes (should I become worried now? ). Anyway, behold below, two variants of the Type 97 Chi-Ha medium tank:
And now, let us look at what the justification of my numbers is. First, it had slightly thicker armour (8-25 mm) than a Type 89 (having 6-17 mm armour). So I just added a single defence dice to account for that. And now to the gun. The earlier variant was armed with a type 97 57 mm tank gun, while the later variant - the Kai Shinhoto was up-gunned with a longer barrelled high velocity Type 1 47 mm tank gun. Penetration values compared [from http://www3.plala.or.jp/takihome/tankguns.htm ]:
Type 97 57mm Tank Gun:
Caliber : 57 mm
Barrel Length : 1.057 m (L18.5)
EL Angle of Fire : -15 to +20 Degrees
AZ Angle of Fire : 20 Degrees
Muzzle Velocity : 350 m/sec
Penetration : 20 mm/500 m
Used by Type 97 Medium Tank
Type 1 47mm Tank Gun:
Caliber : 47 mm
Barrel Length : 2.250 m (L48)
EL Angle of Fire : -15 to +20 Degrees
AZ Angle of Fire : 20 Degrees
Muzzle Velocity : 810 m/sec
Penetration : 55 mm/100 m, 40 mm/500, 30 mm/1,000 m
Used by Type 97-Improved Medium Tank, Type 1 Medium Tank, Type 3 Amphibious Tank
Notice the underlined, the Type 1 47mm tank gun had around twice the effectiveness in armour penetration than the short barrel 57mm Type 97 gun. Hence the increase in hit dice.
As to the speeds, Type 89 was 25 km/hr, while both variants of Type 97 had 38 km/hr, so that would suffice to remove the slow capability (taken from http://www3.plala.or.jp/takihome/yi-go.htm for Type 89, and for Type 97 http://www3.plala.or.jp/takihome/chi-ha.htm and http://www3.plala.or.jp/takihome/shinhoto.htm).
One note, the national trait maybe overpowered now. It seriously requires play-testing, so once some one has time and the wish, let me know how it goes (I can just imagine the apocalyptic picture of swarms of Type 89's or Type 97's, send shivers down my spine). Anyway, any comments are very welcome. Going back to the USSR next, I am in the middle of trying to understand how to get the T-28 and T-35 land battleships to work properly in the game, so the next post may be a bit of fun and giggles project. Stay tuned...
