This is 2011 set, Target Exclusive I believe. There's a companion blue one as well. The UNSC weapons (identified above) and the two backpacks are standard issue grey. The two marines are identical molds with different heads. You'll notice the marine hands are red too. The Elite is the original mold: i.e. no hole in the back. Beyond the figures and weapons there is a two tier bleacher. The black flat pieces are painted red on the sides, a nice touch and very unique. There's two black quarter rounds that connect the two bleachers and of course the center piece with the Halo logo which reads "Red Combat Unit." This set is hard to find, and therefor worth far more to collectors then the original $9.99 back in 2011. Back in the day this was a good troop builder and a good value. Now however, the modern sets include better figures and weapons. One could almost build this set from scratch minus the custom painted flats and the Halo logo brick.

Looks good on display, particularly if you have is blue companion

This is a great set for those who like red vs blue multiplayer. It includes four unpainted weapons, two different red marines, a red spartan, and a red elite. All of the figures are great and it includes a red/black display base with some red paint of the plates and a printed piece with the set name. I'd definitely recommend this to a Mega Bloks fan!
