Probably the longest running and definitely most stable game I've ever been in is three players and four characters. Also a modern military one, so personally I'd be fine with just the three of us and growing if more people come later.

Quality over quantity sort of thing.

You make a good point, and I've had similar experiences myself. 
Bearing that in mind then, perhaps what I'll do instead is to get an IC post up shortly and we'll proceed with just the characters currently posted, and that way if anyone else wants to join in at a later date they can do so. And any other characters we want/need to make we can make ourselves. Nothing to stop any of us from playing multiple characters if we want to. 

I'll try and get an IC post up in the next couple of days, work and other responsibilities permitting.
