correct as-is for version HELM marks modeling

[TeddyThePilot]

According to the DCS WORLD documentation, HELM reticles can display various modes: continuous ring and crosshairs, as well as flashing rings, and dotted rings and crosshairs. A search on the Internet led to the fact that the Shchel-3UM device has only two possible types of markers: two concentric solid rings of the reticle and a solid crosshair of the signal mark. Both markers can either flash or glow continuously and not be displayed as well. The rest of the views are different combinations of these two markers and flashing and no display modes. I also attach the found images of two markers and combination of both ( found by the Google search request "Шель-3УМ" ) photos from а owner of the HELM.
