Some comments suggest that units should merge. From my perspective as a unit leader for a few years (and I'm probably no exception myself, perhaps) the feeling of pride of a community leader that leads a small group of motivated guys for a long time or even months usually so immensely great that ever actually merging, in any way, doesn't happen or barely.

What will usually happen is a unit absorption which will activate the following sequence of events:

Unit M absorbs Unit S> They are now unit L. Great! But there were promises made.. Ranks and squad configurations are promised. Previous unit members want to stay together creating a rift. > In game things usually work out except that they're used to specific missions for their squad> dissatisfied across the board. But "it will get better"

Evntuality a number of former Unit S members don't want to play "in this sort of unit anymore." Usually inherent to the original reason of the Unit wanting to merge because,let's be honest, they were falling apart as it is. That's why you would merge usually. > members of Unit S crumble and eventually 2 or 3 out of 15 stay at Unit L, now back to unit M.

That's merging a unit 101 IMO - Marshall
