Also infantry sections since their snare are in the hand of royal engineer.

Not imo, part of the reason IS where nerfed in their DPS is that they almost always fought from heavy cover. I would rather test moving sand bag and trenches to Ro.E and keep IS DPS strong.
Trench would actually become password protected again but able to be captured and able to dismantled.
This changes would force UKF to include more Ro.E. in their army composition. Any changes in balance then would about Ro.E. and not just IS.
