所以他们是退役后再入役的老兵吗？

我认为Evocati应该是星盟决议部士兵的顶点层级的标准名，然后ultra是称号（狂热者是热忱代祷部的）
游骑兵和狂热者这俩词是在小说中的精英视角里也存在的名词，比如在科尔协议和被遗弃者里

以下纯属个人理解：Ultra是单纯的正式军阶名字，而Evocati或是总称Evocati Delegatus是个军阶也是敬称。后者对应的是人类的士官长亦或是军士长，当过兵或是熟悉体系的话会比较好理解。而为啥人类会叫Ultra，但是星盟会叫Evocati，主要是你不会去尊称敌对势力的士官

mcc中文机翻痕迹很重，错误和前后不一致的地方很多，个人感觉可以参考，但不能当成可靠的官方翻译，一定要追求精准翻译的话小说后面的名词对照表这种相对而言更靠谱其他的就不清楚了

奥特！

还是叫奥特精英罢

简单来说“Ultra”或者“Evocati”对应人类理解军阶概念就是“老兵”也就是“士官长”而且是最高级的士官长，具体着装就是不同类型的白色护甲，说白了就是“兵王”，但并不一定是“军官”。
大家要知道 星盟军制是宗教观念主导下的封建贵族军制，掌握军权的高级军官是与精英的各大氏族长老或族长绑定，而这批人在星盟狂热的宗教观念绑定下就叫"Zealot"。
这其中的区别就在于"Zealot"由于是氏族贵族的出身，进入星盟军队服役的第一天起他们就已经是"Zealot"，至少从战地指挥官或者舰长做起（最典型的就是提尔'瓦达米），而平民出身的精英战士就要一步一个脚印的积累战功到“Evocati”，但由于精英的尚武传统，战功卓著且武技超群的“Evocati”在军中就极为受人尊重的，自然也能在作战中获得一定程度的非正式指挥权 （当代人对这类兵的称呼就叫士官长），甚至进一步成为精英议员进入政治领域。
这种区别另一个体现就是星盟最精锐的前线实战部队“特种作战群”的指挥官多是“Evocati”，最典型的就是“半嘴”，某种程度上也证明了“Evocati”在星盟中的地位，最明显的就是光环2中“半嘴”直接当面质疑真相先知更换卫队的决定并要求议会决断，对此先知只能挠头，仔细看过各本小说里对星盟内部描述的玩家再回看“半嘴”当时的态度，都能体会到“半嘴”当时有多拽------

另外还有一点 涉及到星盟军制，星盟及其军队本质上是舰基势力，军力构成以舰队为核心 空战和陆战单位由舰队搭载 受到舰队主官如舰队司令或至高指挥官指挥节制，而这些舰队主官又由至高议会、大主教、上级部长指定任务并由低阶先知监督执行（监军），星盟舰队主要由三个部门负责管理：决议部、热忱代祷部和安宁部
决议部下属的舰队负责巡逻星盟空间，保护航运和消灭海盗
热忱代祷部下属的舰队负责寻找和保护先行者世界和神器
安宁部下属的舰队负责寻找先行者神器，传教并将新物种引入星盟
由于先行者遗迹对星盟社会运行极为重要，自然引来多方觊觎，自然就有了“海盗”甚至形成了“黑市”，所以这三个部门的职权实际上互相交叉的，自然也就互相制衡

超级精英一般都是高级军官或者老兵，护甲值很高，但是颜色和款式不一样

ELITE ULTRA UNIT – EVOCATI
The Evocati, or “Ultras” as human forces know them, are veteran warriors who have demonstrated the highest standards of military proficiency, teamwork, honor, and devotion to the Covenant. These Sangheili display exemplary martial aptitude but lack the inclination or desire to follow the path of leadership and mentoring. Instead, they find the apex of their warrior career as an Ultra, crowned with glory and guaranteed a position of honor and respect in their family archives and record vaults of High Charity. Few remain at this pinnacle for long, and Sangheili promoted to Ultra are expected to take up honorable posts as seneschals, tread the path of political warfare as a Councillor, or return to their Ministry to train the next generation of warriors.
Ultras are among the deadliest Sangheili infantry available to the Covenant warhost commander, their alabaster combat harnesses marking them as combat specialists able to execute missions for which failure is not an option and defeat unthinkable. Their high cost is justified by their firepower and ability to deploy from low orbit to the battlefield using insertion pods before charging into enemy lines. Carefully consider how and where you will deploy Ultras, or risk drawing the Supreme Commander’s ire if they are expended needlessly.
ELITE ULTRA OFFICER – EVOCATI DELEGATUS
Ultras rarely answer to the warhost commander to which they are attached, though some degree of cooperation and synchronization is necessary to achieve their mutual goals. Ultras elect delegates from among their ranks to take on this responsibility before each deployment, and swear binding oaths to obey their commands until all objectives are completed. These Ultra “officers” hold no official leadership position in the Covenant hierarchy and are not Obedientaries, but they are acknowledged as subject matter experts in the art of war and wield real authority on the battlefield. In human terms, they are equivalent to a Warrant Officer, selected for talents and knowledge which complement the tactical objectives at-hand.
The Ultras are a brotherhood of warriors born, devoted to skill in arms and little else. Those who lead do so from the front, energy blade clenched in hand and plasma grenades primed.

另外说一下以上这些精英称谓或者说头衔的类型，其中minor和Ultra主要是等级或者说军衔称谓，ranger、commando和storm则主要是职务称谓，zealot是精英贵族专属的军阶称谓，虽然这些头衔放在一块，但实际上概念并不一样

一般不是都叫蓝甲红甲金甲什么的吗()

为何不翻译成“奥特精英”
