You Don't Know What You're Talking About

Who is the worst person to talk to about the effectiveness of a tank?

A tanker.

Who is the worst person to talk to about the effectiveness of a rifle?

An infantryman.

"HUH?" I hear you say.

When we signed for our "brand new" M1(IP) we took on a loadout of M900 APFSDSDU.

I was not told how well it performed against a rolled homogeneous armor equivalent.

I was told that it'd punch anything we expected to meet in 1988.

I got told the same thing when we traded the M1(IP) for M1A1(HA).

Go ahead, look up the performance for the M900 round.

Find anything definitive?

It's still classified.

The reason you don't know what you're talking about is that you CAN'T because you don't have access to the necessary information.

Or, if you DO, you're violating your security clearance and should be worried about knocks on the door.

Much of the debate is based on speculation, often informed speculation, but still speculative.

It needs to be said that both sides are lying about how well they are doing, but if Russia was doing as well as they claim then the war would be over and Ukraine would be dead.

Ukraine doesn't seem to be claiming advances they cannot prove to have made.  But they are still lying about individual events.  It's called propaganda.  Look it up.

So far, it appears that T-62M and T-72B3M are the most common Russian tanks at the front and not the T-90M or Armata.  Appears.  I've yet to see a reliable source cited.

Lots of claims on blogs, but no citations.

Yes, that matters.
