Light recon for countering other recon.
Offense: When fully promoted are very effective against other recon units and infantry; can also be somewhat useful in an AA capacity. An extremely fast speed means they can be at the enemy's doorstep in a very threatening manner, very quickly.
Defense: Put down a max rare tank or better and you won't have to worry at all. There are also other recon units that will destroy the ★People's Dagger★ very quickly such as the Orontes I or Hippocampus.
