Actually, there are many instances when attackers used smaller forces and, in fact, in modern combat, we try to use as few troops and materials as possible to fight. This saves lives and cuts down the cost of war. If you'd like historical and modern examples, I'm more than happy to discuss them with you over PM.
As for reinforcements in space, there aren't really any others. The latest fleeter is probably the only other Republic fleeter on the board and [member="Ayden Cater"] is the only OP fleeter that I know of. Actually, until the latest fleeter showed, it was literally just Ayden and I, in fact I remember mentioning on at least two occasions that we were, short of a fluke, the only fleeters on our side that were going to be there. Both both in ships and writers in space, you outnumber us at least 2 to 1. On the ground, we outnumber you, but once the space battle is done, if you win it, you'll vastly outnumber the Republic on the ground.
Anyways, if you want to discuss this further, please feel free to PM me and we can chat it out politely and civilly if you'd like
