Current Finnish OOB - some notes for discussion

[PvtJoker]

More AT related stuff:

I am going to add a 122 H 63 (D-30) AT unit from mid-1990s. This howitzer has a secondary AT role in the Finnish Army and although it is "emergency only", the gun crews are trained for it and the weapons themselves come with a direct fire telescopic sight. LRF's are used for ranging.

The biggest problem I have with this addition is that there seems to be no reliable penetration data for the BK-13 HEAT grenade. Russian Wikipedia lists 460mm, but no hit angle. I also couldn't find the number in the listed sources, so who knows where it comes from. Russian Wikipedia also claim that max. range is only 1 km, but you can find scanned copies of the original firing tables going up to 2 km (somebody mixed up max. range with "direct fire" range to 2 or 3 meters tall target often mentioned in Russian manuals).

In Western sources the older BK-6(M) is also listed at 460mm at 0 degrees. Russian Wikipedia gives 400mm for it (incidentally, or perhaps not, 400 at 30 degrees is roughly the same as 460 at 0). According to the sectional drawings floating around in the net that come for a fairly reputable Western source, the BK-13 has a wave shaper booster and 105mm cone diameter, which would make 460mm at 0 degrees a much lower than expected RHA penetration compared to others of the same era (late 1970s). So, I assume it is actually at 30 degrees, which gives 530mm at 0 degrees. No more than a guesstimate, but then again the SPMBT OOB's are full of them.

I am also going to add a version of the 95 S 58-61 "Musti" recoilless rifles with a LRF since 1995. The Mobhack Guide says that recoilless rifles should always have RF value 2, but I suppose Don and Andy were not aware at the time of writing that many of them are these days provided with a LRFs, which did not exist during the heyday of recoilless rifles.
