Binoculars are currently the most “meh” equipment piece, is far can be great in some situations almost all time is simply unnecessary and a bad investment of silver, more than showel, but I think both should have spacial feature for make them more useful
So
showel
The showel is currently used for dig pit or small trenches for hide a rally point but his usage is very rare, for my pov, then i would suggest a nice change
The entrenchment mode
Showel should have the free mode who is what we already using, and the entrenchment mode, who active a building system who let players build fully fleshed trench or dirt barrier, this feature should be possible just for engineer because it should requires engineer building point for balance
binoculars
The binoculars in game are used mostly by tanker commander for spot enemy in distance, rarely I need say, but as for the showel we can do more
Spotting ability
Binoculars should auto spot enemy vehicles (tank,plane,bike,APC) and construction adding their icon on the team hud, enemy infantry by adding an alert on the minimap of the team telling were they are but without following them, also for every kill of spotted enemy the player who spotted is rewarded with assist point if his marker is still on
