Battle Rifle
http://www.yesalbum.com/v001/thepretenders22/br.jpg
Designed to replace the MA5B Assault Rifle from the original game, it has also been heralded as the "New Pistol". And it lives up to its namesake. With reasonable power, decent rate of fire and high accuracy, it has proven itself to be one of the most versatile weapons in the UNSC arsenal. With a 2x zoom scope, it can be used to deliver three-shot-busts accurately from medium-to-long range. At close range, simply center the target in your sights and pull the trigger.
In single player campaign, is the second-most common Human weapon encountered. Useful against just about any infantry units (save for perhaps the Hunters). In multiplay, appears often in two or more spots on just about every map. Three bursts bring down standard shields, while one headshot results in death.
Pro's
-Accurate /powerful /great all-around weapon
Con's
-Relatively ineffective against heavily-shieded enemies /low ammo capacity
Overall: Excellent weapon. Good for newbies, good for the very best. Just plain good.
