A use for the ingame alliance system would be to allow HC to award Medals and Ribbons to their members.
- Ribbons for participation in campaigns (or wars) against enemies
- Medals for various achievements: reaching different levels in score, number of cov ops, amount of scans, intel gathered, or some daring attack, FC...
Here is what we used back in R4 for a long forgotten alliance... It gave each member the occasion to prove himself and kept them all focussed on a goal for themselves even if they were not competing for top spots.
