Deny it to the Elephant. Problem solved.
Have you ever tried spotting scopes on the elephant? Trying to keep the thing still so he actually gets the sight buff is a chore in itself. He requires a lot of micro but it pays off. Elephant is also really slow and easily flanked.
On another note:
My favorite strategy for Ostheer is based around putting the scope on my half track. With double paks and double mgs supporting it, tanks and infantry cant get past you. You can spot rifles flanking you from miles away and paks can actually shoot at there max range with the LOS provided from the HT. Plus you can reinforce on the go. Ostheer imo REQUIRES their HT even tho its the worst of its kind DPS wise because they only have 4 man squads and rely most on support weapons which take 4 men to recrew without losing a squad.
The only downside to this strategy is that you are VERY vulnerable to indirect fire from mortars and artillery alike (callopies are certain death). This strategy also requires a ton of micro to keep all the flanks covered and the HT well guarded. (jaeger armor commander gives riegel AT mines for HT which is very useful to trap all tanks in the arc of fire of your paks.
This strategy works best on open areas with little to no shot blockers.
I usually go T4 with this strategy and get Pwerfer to wipe blobs and support weapons and a panther to chase down mobile artillery.
This strategy is extremely effective on moscow outskirts.
While the scopes are extremely effective in the right hands and right situation, it requires a lot of micro and is in no way OP. Easily countered by indirect fire as well.
