Well here are some ideas maybe interesting for the game
Airbone Infantry
Maybe add a secret unit that can overfly a province to attack beyond the front or make a unit that can brings commandos (or parachuters) beyond the line in a little range tha increase when you improve the unit(s)
Naval mines ships(miner)
This will be a naval ship that add 1 mine when lvl 1, 2 when lvl 2, and will increase the damage that does the mines and well they will be good with ships and well 1.5 or 2.0 with subs and 0.0 with Minesweepers(the mines) and the ship will only put mines but ironically are 0.0 with the mines and well
just supose that is a little ship that put mines
Minesweepers
Anti-mine ship, well they will carefully and safely destroy the mines (range 20km) ships attack 0.5, subs attack 2.5
Kamikaze aircraft
The name said it all a plane that attacks its objective and explodes it have to do more damage than a tactic bomber amd it is very cheap to make
you can improve the idea YOU THE COMMUNITY
Vote which ones do you like more
