The manga adaptation of "War in the Pocket," currently serialized in Gundam Ace magazine, is not only full of characters and story developments that Hiroyuki Tamakoshi continues to draw while battling illness, but it's also packed with charm, including the appearance of mobile suits different from those in the OVA.
The story depicts "Operation Canossa," which was not seen in the OVA,
and the mobile suit piloted by Andy Strauss of the Cyclops Corps during the operation is the Rams'gok.
This Rams'gok was built using the HG Char's Z'Gok kit and based on the image depicted in the manga.
