Posted here since I don't really think it's big enough to warrant its own thread.
60mm HVMS
Development of the 60mm High Velocity Medium Support weapon (HVMS) began in the late 1970s as a joint Israeli-Italian project. The original intent was to develop a rapidly firing weapon with superior armor penetration and ballistics compared to existing 20-25mm autocannons. The new weapon was planned for mounting on light platforms such as the M113 and similar vehicles.
M113 with HVMS mounted
While it was planned that the Italian-Israeli cooperation would result in a single common weapons system, a few variants ended up being developed. The Italian variant was fitted in a specially designed turret and loaded from two 32 round drums. It is claimed that this gave a rate of fire of up to 100 rounds per minute.
HVMS fitted to Piranha 8x8. The specially designed turret weighed approximately 5 tons, and the main armament could elevate from -5 to 40 degrees.
The Israelis developed several different variants. They also fitted the 60mm HVMS to a specially designed turret. The Israeli turret was much lighter (2200 kg vs. 5000 kg), although the Italian turret could be equipped with up to two TOW missiles.
Third, the Israelis developed a version of the HVMS loaded either manually or with 3 round clips. It appears that this had a somewhat lower rate of fire than the drum fed variant, but could be more easily fitted to existing vehicles.
Neither the Israelis nor the Italians ever deployed the 60mm HVMS, to my knowledge. However, the system did have a minor export success; Chile bought roughly 150 of the guns to refit their Shermans and Chaffees with more modern armament. While the 60mm gun did not have adequate performance to engage high end Soviet tanks such as the T-64 or T-72 frontally, it would be enough against other tanks in use in South America (such as the T-55, TAM, AMX-13, or SK-105).
The guns were sold to the Chileans in 1989, and were fitted to their Shermans and Chaffees in the 1990s. They were retired in the early 21st century when the Chilean Army replaced its Shermans and Chaffees with upgraded Leopard 1s.
The 60mm HVMS used a unique 60x410mm round as ammunition. It appears that two main rounds were developed; an APFSDS round, and an HE round. One source also says that the Israelis developed smoke and incendiary rounds, though I have found no concrete information about them.
As one would expect, the APFSDS round was the main antiarmor round. The dart weighed 870 grams (compared to a total projectile weight of 6 kg), and was 292mm long with a 17mm diameter (length to diameter ratio of 17)
Chamber pressure was roughly 430 MPa. The muzzle velocity of the round was quite high, at ~1600 m/s (roughly Mach 4.7). Penetration was claimed to be superior to 105mm APDS ammunition, though I imagine later L7 APFSDS would outperform the 60mm.
(This sheet gives slightly different specifications for the APFSDS round. The other specifications appear to be for the Israeli rounds in use by the Chilean Army, while this one is a Belgian round probably built for the Italians.)
60mm APFSDS compared to other rounds
The high explosive round was fairly typical, with a 2.9 kg payload.
This claims to be the wreck of a T-62 used in testing of the 60mm HVMS by the Israelis.

Say WA? The election was November 8. Kristallnacht was the evening of November 9 to the morning of November.
Shit. Fucking liberals can't even be asked to look up a date on The Google?
Nah. The more apropos historical allusion is that November 8 was the anniversary of Hernan Cortez and his band of Deplorables entering the gates of Tenochitlan, an event that later saw the extermination of the Aztec Empire.

Hmmm. I guess there's another Joe Walsh other than the guitarist for The Eagles.
Good to know.

Scolopax reacted to steppewolfRO in Wargame Thread
Well, Israel DLC is upon us...and indeed the chat was muted few days but many bans were handed or at least this is what I gathered from Eugen forums.
Feels a bit like pay to win as Israel have some unicorns that outrange most of the stuff red can bring on the field.
Weak points:
Really bad AA (base Chaparral, base Hawks); Pivad + Stinger is decent but Red helos may counter it or is seadable. 20 mm non radar SPAAGs are fine but need to be close...so it is one of the decks when you may need two cards of ASFs; Baz Meshupar and Barak II seems better than F-15s / F-16s US can field I was fairly succesful against them with Chinese SU-27 or Polish MIG-29 using their longer ranged BVR missiles No IFVs but this may be supplemented by Merkava II transport and Achazarit with 3 MGs...although I would have liked one auto-cannon option at least; I feel that Merk II is kind of too well armored.. Unicorns are Merkava III Baz (excellent Lahat range), Nimrod ATGM and transport helo, Pereh (although I don't like it tbh), Nimrod, Lavi
Lavi is an exceptional survivable bomb truck if micro managed. Kurnass (LGB) + Kurnass 2000 (SEAD) may be paired for a nice strike train that goes with the same speed and turning rate...Kfirs are also interesting for small tactical games, I especially like the anti-helo capability of Cat C ASF Kfir
What annoys me most is Maglan (ATGM 10 man elite recon team ) because their mission seems to be behind enemy lines and as is pictured in the game with Spike ER they're great to be used as spearhead of your main force .. they seem somehow OP although they may be countered with scoped rifles recon teams, mortar (although slowly), rocket planes or helos.
Another issue is the 10 ROF of Merkava, I think it should have been stayed at 9. Overall Israeli armored force is over-modeled but it's doable to defeat it.
I really like the combo Merkava II IFV like + line infantry, it's an excellent combo which makes this faction defending ground quite easy and difficult to be displaced from a zone...you only have to worry about enemy air power but it's doable.
It's a faction against which you can use air power a lot...and imo it hurts 10vs10 a bit although is not such an issue in smaller games. Perhaps some small nerfs will follow but overall it's a different gameplay
I am looking forward to Yugoslavia, that should be a badass mech deck (my prefered play style).
