Before the start of the TV anime
there was a 4 minute special featuring the three main seiyuu,
Touyama Nao, Sakura Ayane, and Minase Inori.
The Military anime itself is only around 5 minutes each,
including the theme song.
There was a very short introduction of the Military anime and characters.
The three main seiyuu appeared wearing military outfits.
They went to a JSDF Center "Rikkun Land",
and played around in a helicopter, flight similator, and tank.
