Winter Operations - Kharkov '43: Round 3

[Steel God]

I made some tests and i was only able to release the sicherung division. The LSSAH tank didnt released even if the soviets take all the 100 VP and 250VP objective points

That would be correct as I assume the rule works on HQs, and since the regimental HQ is stacked with the SS armor, the entire "unit" is in the same hex and will only release when that hex is spotted.  I agree with Ricky's assessment, they won't release unless you're already well and truly screwed.
