Encirclement vs. UKF Sim City?

Hi there, I’m a fairly new player and just began dabbing int PvP after spending most of the time in Automatch vs Ai, and I’ve bee getting stomped pretty hard by Sim city strategies playing as Ost or Okw. The strategies I’ve seen suggest ignoring the sim city and attempting a base rape, but I rarely see the encirclement doctrine suggested. Is it a viable strategy, or has it become too difficult to attempt against real players to be of any use?

I'm unsure what game modes you mean but I'll assume the larger team games of 3v3 and 4v4.

I'm assuming that you're having this trouble in team games. If that's the case then I find the Ost's Mortar Halftrack to be one of the best solutions as its incendiary barrage ability takes care of them fairly well. 2 mortars or sieging the emplacements with AT guns supported by infantry is also a good way of taking them down.

For OKW the Feuersturm doctrine's Leig flame shells should work as well. If the emplacements are surrounded by buildings then consider getting a few flamethrowers as they will destroy them easily. Incendiary rounds from both the MG34 and 42 will also destroy emplacements very quickly.

Encirclement is a tough doctrine to make work since it only works on very few maps. There are far better and more efficient commanders that you could choose to specifically take on sim cities like Spearhead or Festung Support (if that's the right name). You can try to make encirclement work but it takes a lot of planning and the game would need to drag out into the very late stages.
