[0085] FIG. 49 is an isometric depletion from an upward looking vantage point, at a slightly different view angle than FIG. 48, showing the engagement of the upper stabilizing arm section (21) and upper flange (21U) with the assembled floor sections (14, 18), as well as the spatial relationship between these elements in assembled form and the Quadcon base (5) and pin (7). Pin (21P) (tapered pin end opposite pin head shown in this view) attaches upper flange (21U) to both floor sections (14, 18) via holes provided therein for such attachment.

[0086] FIG. 50 is an isometric depiction showing the partially assembled roof in detail with 3 E-glass panels removed. Optional lugs/attachment means (81L, 85L) are shown for the middle transverse roof beam (81L) and the transverse roof end beams (85L).

[0087] FIG. 51 is an isometric depiction from a downward view-point showing a fighting position (2) embodiment in accordance with the invention. The entry cover (11) can be seen clearly in this Figure, which may function to reduce tripping hazards and ease of entry and egress.

[0088] FIG. 52 is an exploded view isometric depiction of the full floor panel. Also shown are column attachment points 10A wherein flat bottom pin (6) is used as a column pin to attach the bottom of the four columns (30) to the floor. It has a flattened bottom edge allowing it to be placed more closely to the floor. This reduces the rotation or angle, i.e., the extent and amount to which the columns may move once they are pinned in place. This creates greater stability for the structure, including the roof in certain embodiments of the invention.

[0089] FIG. 52 also shows, as discussed above, that the inner floor panel maybe split into separate pieces (10, 12, 10) which are slidably engaged, via engagement members 10E and 12E in order to reduce the weight of a single piece inner floor panel. They also may be latched together in certain embodiments of the present invention with latches (71) similar to those shown in FIG. 7A which may be used to latch together window sills, one to the other. The sills may also be provided with handles to facilitate their easy handling during assembly and disassembly and also to prevent pinch points. FIG. 52 shows the slidable engagement of side floor panels (18) to the inner floor panel via engagement members 10E, 12E and 18E.

[0090] Weapon mounts (35) may be added in certain embodiments of the present invention. In embodiment of the invention weapon mounts may be placed into a cavity (75) between the inner and outer walls.

[0091] In certain embodiments of the invention, a ladder may be used for access to the guard tower of the present invention. In embodiments of the invention, a stairway may be used for access to the guard tower of the present invention. If desired, the guard tower stairway may have a railing.

[0092] In embodiments of the invention the roof system may have anchors/lugs (81L, 85L) attached to the top of it. Latches may or may not be used in embodiments of the invention to link roof elements together.

[0093] Floor armor plates may be provided, and they also may be provided with grip tape to reduce slipping hazards. In embodiments of the invention, latches are provided on the sills to connect the individual sill pieces together.

[0094] The appended claims are not intended to be limited to the features shown in any of the particular embodiments described herein, and as such are entitled to the scope of a full range of embodiments that fall within their metes and bounds.
