Ever wonder just what some of the things they are saying means? You have to pay close attention to pick up on some of this stuff. Such as CAS stands for Conversion Armor System.
Well I've put together a list of battle modes that took place during the series in numerical order. Just what are battle modes, you ask?? Well, each battle is scheduled with a set of guidelines that the teams involved must adhere to. Battle mode is your primary guideline. Then you have secondary guidelines such as the use of arsenals.

MODE # DESCRIPTION

0973 This indicates a ground battle. If you recall when Harry Champ first took on Bit and the Blitz team this battle mode was used. Basically, it was a ground/blind battle taking place in maze- like surroundings with Leena to the victor.

0982 Probably the most common battle mode. Each team can only fight with a stipulated number of Zoids. Most of the time there is no restrictions on arsenals.

0988 An old-fashioned show-down limited to long-range weapons. This battle mode was used during the Blitz team's first encounter with the Fluegel team. They were limited to 6 shots apiece.

0992 A one-on-one battle. Commonly with no restrictions on arsenals. This is the battle mode used when the Elephander took on Bit and his Liger.

0999 The infamous Dark Judge's favorite battle mode. There are no rules, you either WIN or you LOSE. We see this one often.

6990 Battle mode used during the arcade game. It indicates a shooting challenge. In addition, this battle mode allows for mid-battle entries. We see Vega defeating Bit and Jack Sisco during this battle.
