A single soldier unit is assembled from just nine parts in total (including its weapons). The difference between Zaku and GM is just the face ^^; Check out the construction manual in my previous posting.
As usual, Bandai is smart... ... Luckily I'm not a huge fan of SD Sangokuden ^^;
Apart from the troubles of getting all the six units, the amount of painting is significantly more than the usual SD Sangokuden kits.

A brief introduction of the characters above and others:
* Guan Ping (关平) - Guan Yu's son.
* Yuan Shao (袁绍) - A powerful general who fought against Dong Zhuo (董卓). His forces were eliminated by Cao Cao in the famous Combat of Guan Du (官渡之战).
* Tian Feng (田丰) - Military adviser to Yuan Shao
* Zhou Cang (周仓) - A powerful warrior loyal to Guan Yu.
* Cheng Yu (程昱) - One of the best military advisers who served under Cao Cao.
* Guo Jia (郭嘉) Virsago - One of Cao Cao's military advisers.
* Chao Ren (曹仁) Gundam Leopard - Cao Cao's cousin, a skillful warrior.
* Chao Hong (曹洪) Gundam Airmaster - Cao Cao's cousin, served Cao Cao as a warrior like his brother Chao Ren,
* Xu Zhe (徐庶) GM Sniper - Served as Liu Bei's military adviser before Zhuge Liang came.
* Pang Tong (庞统) Gun-EZ - Like Zhuge Liang, he became one of Liu Bei's military advisers.
* Shima Hui (司馬徽) Guntank - A friend of Pang Tong.
* Lu Su (鲁肃) Rick Dias - A diplomat from the Kingdom of Wu.
* Chai Mao (蔡瑁) Gyan - A powerful marine commander of Cao Cao. Cao Cao was tricked by Zhou Yu in believing that Chai Mao was a traitor in his army, which resulted in Chai Mao's execution. His death is one of the major reasons for Cao Cao's defeat in the Battle of the Chibi (赤壁).
* Chai Zhong (蔡中) R-Jarja - Chai Mao's brother.
* Wei Yan (魏延) Vigna - One of Liu Bei's most famous generals.
I believe the Gundam in the top right portion of the picture above is Guo Jia (郭嘉) Virsago.
