River class:

Although it is a bit of an off-shore unit, not a River gun boat.
The thread where I asked about Sabre:

Note on Scarab: it has the same unit class as the SAS PV's.
Personally I think the crewed Icons are worth keeping, it only covers three unit slots, and it's not like your running out of space in the UN OOB. Same for the Large ship, I can give an example, in DosMBT I did a senario of Spain invadeing Gibraltar, one of the fun supprises I wanted to have was a large warship.
There's also a few formation error's I belive as well.
