Unga Both a verb and a noun, to unga is to charge or otherwise do something with minimal thinking or planning. For instance, "Delta is ungaing off again..."

Where as a noun, it's basically the same, just a marine who is focused on killing and isn't really planning anything out. For instance, "Delta is full of ungas." Sometimes it is used as a chant, like "unga dunga". Very powerful word.

Unga Juice A noun. Unga Juice is a custom made chemical concoction of multiple healing chemicals (akin to the Emergency Injector) made by doctors to be either put in flasks or a liquid tank for distribution. Filled with possibly the following. Kelotane, Bicaridine, Tramadol, Tricordiaze and Dermaline. Though there are many variants of Unga Juice, this is just an example of one.
It is said in the ancient scripts that unga juice comes from the god Mo'ya Unga, the father of all ungas. Wise worshippers of this belligerent god are imbued with the knowledge to make it. There are many different recipes, according to his followers, and all of them are right. Some say it was a 1 part each of kelotane, bicaridine, and tramadol. Some say it is tricord, kelo, and bicar. Some say oxy, tricord, bicar. Any combination of chemicals that heal you fast, and let you UNGA.
