No. The supporters must be directly behind the supported. Not just further back.

Not supported as the confused chaps are not behind

Supported as the cool guys are behind the happy guys and there are 2 supporting 4. 2 Bases at least parts of which are to the rear of happy and the happy guys are to the front of cool

Basically this



But just to complicate it:

The support is worked out by bases. i.e. the supported unit does not have to be in front of the whole supporting BG, just enough bases to count (half its original strength), and only the number of bases of the supporter needed (half) have to be between the 2 lines as directly behind.

So you could end up with this, where A is not supported, but B is



as A is not in front of 2 bases of the supporter

crystal clear ! thx
