In case you wanted to make your character extra snowflake, some TE players have devised a serialization method for their suits. This has been added to the wiki as the Suit Type Designation system (STD). STDs are optional and available for everyone.
To give your character an STD, follow these steps:
First, Faction:
AC - Armor Corps
MQ - Moqaddas
HB - Hanse Behorde
TE - Tumblr Engineers
GI - Green Initiative
PC - Phoenix Collective
Next, Size Class:
XS - Mesh
LS - Light
MS - Medium
HS - Heavy
FS - Fortress
Then, combat purpose, followed by the first letter of the suit's name:
A_ - Attack
D_ - Defense
S_ - Support
And finally, variant/version number, followed by any possible squad callsigns or such:
Example: White Falcon Kai - ACLS-AW6/G2 (Armor Corps Light Suit, Attack, White Falcon version 6, Gravediggers 2)
Other Methods
There have been propositions for changes to the second part of the STD, due to the majority of TE Suits falling into the "Attack" category.
Combat Purpose defined by engagement range:
CR - Close Range
MR - Medium Range
LR - Long Range
AR - Artillery
Combat Purpose defined by Specialization:
A_ - Assault
O_ - Ordinance
S_ - Support
Unique Methods
There may still be those who prefer to use unique serial numbers, if they chose to do so at all. Serials that don't adhere to any common system are collectively referred to as Alternative Individual Designation Systems (AIDS).
