Moving into an assault hex

[plloyd1010]

To clarify, and show off graphical skills again, while I wait. The situation looks like this:

   

Using a tank  leader activation, one of the tanks in 0504 moves into the assault hex. So when it moves and assaults, can the 2 disrupted tanks join the assault?

BtW: We already played it out as though they could. Result was one disrupted tank became demoralized and the new tank became disrupted. German infantry is holding up well.
