United Colonies of Mankind (UCM) - Longbow Howitzers
The Longbow is a one-man crewed, multi-role artillery unit, built around a rotating self-loading ammunition chamber, in much the same manner as a revolver of old Earth. On the Longbow, this can be rotated to select one of three different rounds; armour penetrating (anti-tank), high explosive blast (anti-light vehicle/ structure) and Smart Smoke.
Smart Smoke can be dispersed over friendly units to screen them from enemy fire or can be used offensively to disrupt enemy fire. It's a particularly innovate creation from the UCM experimental Sci-Tech labs, as it carries an exothermic component to skew thermal imaging. The round also delivers micro-drones, which facilitate the instant breakdown of the smoke on command, allowing friendly shielded units to open fire with a clear view when needed.
The Longbow is designed to be carried into the fray by the Raven-B Light Dropship, giving UCM commanders the flexibility and speed needed to deploy and re-deploy at speed. It is surprisingly large (slightly larger than a Sabre MBT) for a Raven-B portable unit, a fact which can be explained by its relatively low combat weight and modest armour protection.
