Inflatable tanks are being used on battlefields in Ukraine. How hard is it to tell the difference?

• Dummy tanks have been used since WWI and were used to great effect during WWII.
• One of their primary purposes is to get the opposing army to waste money and ammunition on a decoy. 
• High-tech equipment makes it hard for even the best inflatable tanks to work.

Recent videos appear to show inflatable tank decoys being used on the battlefield in the conflict between Ukraine and Russia.
