Makes this old tanker enormously proud.
There are unconfirmed reports that American tank crewmen and tank mechanics are getting on to Twitter to tell Ukrainian defenders how to disable Russian tanks.
In tanker school, the merits and weaknesses of presumed enemy tanks were drummed into us over and over, the better to set up a disabling or killing shot on the tank gun. Good information to share right now.
It's kind of funny; I trained as a tanker towards the end of the Cold War, when it was assumed that any enemy we faced in battle would be fielding Soviet-made tanks, and any allies we had would be using Western-built tanks. We trained rigorously in tank recognition for this reason.
Then the Gulf War came along, and we had to face the fact that at least one ally, Syria, would be using Soviet-made tanks like the T-62, while our enemy Iraq, in addition to operating huge numbers of various Soviet tank models, also used Western-made tanks like the American M-60 and the British Chieftain.

First Armored Division out of Ft. Knox, KY. Fought Rommel's troops in North Africa, and was in Italy for most of WWII. Y'all are a special breed. 
In humankind to see the rest of the world coming together and helping in all these creative and useful ways. Hell, even Anonymous came out from the ether to help.
Torsion bars, end connectors, center guides and sprockets are weak areas for kinetic rounds.
But nothing says hooah like a FSDU sabot round to the underbelly. 
When I told him about this he demanded “show me how to do Twitter.”
and you.
Was in the "Seven Steps to Hell", stationed in Bad Kissingen, Germany, late 50's - early 60's.
After serving, got degree in mechanical engineering and retired as general manager for a division of GM.
Best place to hit a tracked vehicle is either the drive sprocket or the idler wheel opposite the drive sprocket.
Drive sprockets are usually attached more firmly than the idler wheel because the drive sprocket is providing
the horsepower/torque. The idler wheel however is not over-engineered, much like a car's fan belt idler, it's
just supporting a bearing and keeping the proper tension on the track so the drive sprocket stays engaged.
Drive sprocket & idler are always higher up than the "road wheels", road wheels hold the track on the ground,
tracked vehicles can lose 1 or 2 of these without affecting it's ability to move. Ignore all of the "intermediate"
idlers, the ones above the road wheels if so equipped.
The "KILL SHOT" is the main idler wheel, without them there's to much slack in the track for the cogs of the
drive sprocket to engage properly. It'll stop moving within a few feet.
Anybody with a twitter account (I don't have one) is encouraged to spread this information anywhere you see fit
to help our fellow human Ukrainians.
