SENJO<br/><br/>As soon as the Leftenant ordered the Hab Block be held as a defensive position I began. The priority was to set up the sentries with the optimal field of fire and that required some conditionals. I dropped the two drums and the ammunition bags in the centre of the main floorspace and spoke to Mengsk.<br/><br/><strong>"Sir, there are two tactical options for positioning the guns, the first..."</strong>I stopped and scanned about. Leaning against the wall of a dwelling unit was a broken piece of what appeared to be interior ceiling tile, a half-metre square of white foam-plastic. I went to it and picked it up, pulling a marker device from my coat inner pocket and returning to the stacked drums. I used the drums as a makeshift desk and began to quickly sketch out the Hab Block and adjacent walkways using their real dimensions as I had calculated by eye.<br/><br/>(http://i279.photobucket.com/albums/kk137/HaibaneR/Hab-Block-Defence.jpg)<br/><br/><strong>"The ideal location for both guns is here... and here..."</strong>I marked the gun positions for A and B outside the Hab Block doors facing down the long walkways.<strong>"Each gun can sanitise in three axes, the main one being down approximately one hundred metres of access corridor. They can also fire along the length of the Hab Block. In a scenario in which the guns fire <em>into</em> the Hab Block, the most secure location for the platoon CP is just <em>here</em>, inside the corridor that accesses the School or the corner adjacent to the stairwell. However with both guns outside the Hab Block I will need to clear this walkway <em>here</em>."</strong>I marked it with a 'C'.<strong>"I'm willing to do that on my own, I can move quickly and almost silently. It should require less than one minute."</strong><br/><br/><strong>"The second position is <em>here, within</em> the Hab Block itself, gun A facing left, gun B right but placed offset so that it covers the stairwell and School-Dining Block access. The guns can elevate thirty degrees so in the event of targets accessing the Hab Block's upper walkway, or the stairwell, those zones will be covered. I will limit the gun scanners not to sweep for targets behind them, giving this area here as the platoon CP."</strong>I indicated a zone in a circle between the guns.<strong>"It is exposed however, though some of the dwellings may provide hard cover."</strong>I looked around at the debris left by fleeing families.<br/><br/><strong>"I am constructing a scenario of the sequence of events here based on what we have found. The cleared out Vehicle Bay and Wood Shop and the welded shut walkway door near the Wood Shop suggests the colonists retreated from the outside of the colony structure to the interior. The barricade there~"</strong>I touched my marker to the far Hab Block door near the proposed site of gun B,<strong>"~suggests that was their other perimeter, though a weak one. A sweep of the School, Dining Block and Commissary should confirm this. Whether the last stand was in the School-Dining zones or on the upper level of the structure would be determined by whether the attackers assaulted from ground up or from the upper level down."</strong><br/><br/>I was still considering a scenario where the colonists had ruptured into two opposing groups and fought among themselves. I had many questions however, the most pressing being the source of the ground haze and the others should be answered upon access to the colony's mainframe. As soon as our defences were established that was the next task.
