well, that's only for a eating a cav charge.

I rarely let my swords get charged by cav.

I prefer the normal formation of rank 2 and change for swords.

if the cav is charging, I would sometimes make a wedge and counter charge then switch to close to flank the cav.

this is crazy but it occasionally works.

I think hold hold does a lot more than deep ranks.

you can use swords as spears for pinning if using hold hold
