FYI, sturm offizier aura does nothing for LeIGs despite the symbol floating above them. Placebo affect is real though.
It does reduce the reload time.
Please correct me if I'm wrong but the Sturm Offizier aura in the modding tools seems to reduce the ISG's reload time by 9%.
Here are the full effects:
Target Effect Infantry type units but not Officers, HMGs, mortars or the Raketenwerfer +10% accuracy HMG type units (MG34) +10% accuracy Mortar type units (not the ISG) -9% reload time AT gun type units (Raketenwerfer and ISG) -9% reload time
You are absolutely right. It does reduce the reload time and LEIG can continuously bombard the emplacements. Poor thing can't even have 24x7 brace on.
