Titan, CONGRATULATIONS on the Military. You need worry about the mosquito anymore...
Well, I got the mosquito and the guardian (clip).
Mosquito first: Looks great in the picture. But reality is that the handle is just too small. No matter how I hold it, and I have small hands, I don't feel like I have a good grip on it. The chisel grind also doesn't seem to track straight for me when I try to cut something straight with it. I compared it to another bug i have, the Spyderco dragon fly. The dragonfly has about 3/8" more on the handle but is a thicker across and with more curvature. I feel very secure in the grip with the dragonfly. Also, while the dragonfly blade is about the same in length. the flat grind makes cutting so much better and easier. Then again the dragonfly is a folder and more twice as expensive.
I don't know if anyone is thinking of the mosquito as a social backup... DON'T! There is just no grip there for hard use. Now, if this knife came just 20% to 40% bigger, we got a serious tactical knife.
Now, the guardian. This knife I like. It's also chisel grind and I have the same problem getting it to cut straight. But, I would use this for utility... The blade stock is 3/16 thick and 3/4" wide but, as Cougar mentioned, the tang probably doesn't extend throughout the handle because it's forward weighted. The handle itself is on the thin side and has a slight index cutout, and a built in angled guard. From the bottom guard to the pommel, the handle measured about 3.5". It has checkering and ridges but with my small hand I feel like I have just a good enough hammer grip. Good thing the guard because I wouldn't be confident that my hand wouldn't slide up on a powerful thrust without it. The sheath comes with clip as well as a lanyard. Using the clip, the sheath seems set up for a cross draw or behind the back for righties. The magnets in the sheath holds the knife well but allows for an easy draw. I like it. I have to do some serious slashing and puncturing before I can say more... I do think the knife will serve amply as its name suggests as a good backup. I think this knife at it's price range is an alternative to the CR&K stiff kiss. Truthfully, I never handle the kiss but was never interested because I don't like the kiss' handle nor the bulky sheath.
Both the mosquito and the guardian came with less than razor sharp edges. But being AUS8, I think it will be easy to reprofile the edge to a sharper edge.
