HEDGEROW HESCO
I modded a hedgerow icon and put it in the game:
PROTECTION
Hedgerow Hesco will offer the same protection as hedgerows. SP hedgerows include a large earth mound, so it may be about right; but not quite as good protection as the multi-hex Hesco infantry base. You could consider the infantry base has additional built-in protection.
SCALE
These Hedgerow Hesco are larger than those around the multi-hex infantry base. IRL the Hesco you see around large airfields tend to be larger than the Hesco you see around smaller remote bases.
HEIGHT
Map editing will let you change the height of the Hesco wall, just like we can with hedgerows.
MOD COMPLETION
21 icons make up each zoom.
With 6 zoom levels 126 icons would have to be edited, and put in shape files. You can get away with editing only 42 icons if someone has a copy of SP1 or SP2 and DOSBox.
Here’s a thread with more information about zoom levels and using DOSBox to create icons:

Here’s the zoom 4 hedgerow icons that would have to be modded:

The angled hedgerows may be a bit tricky to mod, but I think it could be done. Could even make some sort of sandbag post for some of the corners. A nice thing about the Hesco icons is if they don’t line up with each other precisely that will just make them look more realistic.

MAPS
If this mod was finished and installed, be aware that all maps with summer hedgerows will now have Hesco walls instead. But you can easily switch your Hesco and Hedgerow shape files depending on what you wanted on your maps.
