The Rhino SMG is a projectile weapon used by the Infiltrator class in the game Tribes: Ascend. It is an automatic medium-damage projectile weapon. Its projectiles have excelent armor-piercing capablities, making the Infiltrator one of the best Light-Armor class for reliably taking out Heavy-Armor players at safe distance.
"A silenced SMG, the Rhino has a low report, revealing the Infiltrator from stealth for only a few seconds when fired." In-Game Description.
The Rhino is an automatic projectile weapon with a high rate of fire. It is not a hitscan weapon so the player must lead their targets a bit. When the Infiltrator fires the Rhino while in stealth he is only revealed for a short time before becoming invisible once again.
