Back in the early days of the HCS two types of IFV were introduced, the TRV-5 Tapir reconnaissance vehicle and the TRV-7 Aardvark troop carrier. The Tapir was a tremendous success and has been built in the hundreds of thousands, the Aardvark was a bit of a failure and it's job was soon taken over by the Tapir too. Several thousand Aardvarks were built though but they were reasonably quickly relegated to reserve and training units.
The final 50 Aardvarks have now been withdrawn from service though nearly 200 remain on the HCS "books" in storage. It is likely the HCS will try and sell them to the Aritans who already operate around 150 ex-HCS Aardvarks.
The wheeled APC the WRV-9 Armadillo has also been withdrawn. Only 450 of these were ever made and they seldom saw any action though have been invaluable for training units acting as the "enemy". However now they are starting to seriously age and it has been decided to withdraw them. Because of their very worn state it is unlikely they will find any buyers.
