When large scale events (steel fortress/modern combat) are not live, weekly events could be added to join the player base together and reward silver orders. These events could be campaign specific (ex. Normandy one week/Moscow another week) and setup as a rotation. Offering weekly rewards for playing a specific campaign could consolidate the player base while helping the silver order shortage.
I would very much support this. I would be happy with orders, but you could even give small other things (wrapped rifles for Moscow as an example).
Also a Normandy event could get M1A1 carbines for airborne. I would rather things like this rather than completely different weapons.
