I do not know what exactly you are trying to prove with the shot of the, to use your words "wrecked abrams."  The damage is obviously from an IED.  There is no specific scarring on the armor or blastpoint as you would expect from an RPG or ATGM.  The damage is wide spread with no clear focus.  Now, some of those IED's are awfully huge up to the size of several 500 lbs (roughly 250kg for our European friends) bombs strung together.  Detonated in close proximity to any military vehicle is going to yield some significant results.  

However, contrary to your goal of showing that the Abrams is weak these pictures show that despite having a large and powerful explosive detonation near to the tank, the damage remained external.  The tank is a mess, but looking at the tank as a whole I am sure the crew survived which is a testament to just how TOUGH these beasts are. 

In reference to the heat signature: what, exactly, do you think those pictures show?  Two hot Abrams.  Hmm.. interesting.  What is the context of the photos?  How far after sundown were they taken?  If those tanks were in the sun the metal is going to get damn hot and retain that heat well after the source is gone.  In fact, thats how a lot of Iraqi tanks in Gulf War I were picked off.  They got hot during the day and when the sand around them cooled at night they were like beacons and were insanely easy to spot.  Of course, someone who claims to be so knowledgeable about tanking and warfare in general would realize that as a distinctive possibility and not just jump to wild conclusions about heat signatures.  Not to mention the engine on the Abrams is in the ass of the tank...

Random, out-of-context pictures on the internet do not validate an argument.  Same as pretty graphics won't save a presentation without the facts on which they are based.  The pictures must stand upon the argument, the argument cannot stand upon the pictures.

Sure a 250kg IED is a huge charge but a Leclerc or a Leopard would have survived that , most probably .

As far as the night vision: I figured they were taken at night, the question I posed was WHEN at night.  Just before morning?  Just after sunset?  Middle of the night?  Have those tanks been moving around a lot or idling a while?  Steel will retain heat for hours, that was my point.  What are the context of the photos?  Saying they were taken at night does not present any new information, or provide any context whatsoever.
