There is BUG in W:ET witch allows player to have ZOOM for weapons witch have no zoom ability.
I was died, and spectrated covert-op with garand in zoom mode.
I was engineer with thompson and after I respawned, I was have zoom on my thompson. But I couldn’t do unzoom with my “alternate fire” (becouse thompson have no secondary fire
).
In this location is DEMO size 441.131 bytes witch I recorded (little too late) but in this demo you unfortunately can’t see zoom for thompson. You can see my thompson is moving too slowly (becouse sniper zoom).
After enemy was killed me, and I was revieved by my medic, ZOOM is gone.
I was thing this zoom will be available to see in demo, but I was wrong
I didn’t capture any screnshots 
P.S. sorry on my english
