Trying to find a game

So I could use help identifying the name of a board game I enjoyed as a child. It was a 1v1 game with little plastic rectangle half boxes with labels on one side. It was designed so only you could see the label of your units, with the other person having to send theirs/receive yours blindly. You hid a central piece on the board and tried to blindly fight your way to your opponents. I believe the units had numerical health values so the one with the higher value lived while the other died. Possibly special moves depending on the unit . This has been killing me for years now, so an answer would be amazing!!!
