Title: Military target system

Description:
FIELD 
     This disclosure relates to the field of targets for military target ranges. More particularly, this disclosure relates to a portable target that is durable, moves accurately when hit by a fired round, and does not require resetting after impact of a fired round. 
     BACKGROUND 
     Improvement is desired in the field of targets of the type used to train military personnel in heavy caliber weapons, such as 7.62 mm and .50 caliber rounds, and other common training rounds, such as 40 mm training practice (TP) rounds, 40 mm high explosives (HE) rounds, 20 mm cannon TP, HE, and 25 mm TP and HE rounds. Typically, such rounds are fired by heavy machine gun systems, which systems are often mounted on rotary and fixed wing gunship type aircraft. 
     Disadvantages associated with conventional targets include a lack of durability which leads to heavy maintenance costs and difficulty in observation of hits on the target. Attempts to provide targets on which hits may be observed typically disadvantageously results in targets that must be re-set or replaced after the hit. 
     The present disclosure advantageously provides configured to withstand repeated hits from military rounds, moves in response to a hit to indicate that a fired round has hit the target; and is immediately ready without the need to be reset. 
     SUMMARY 
     The above and other needs are met by portable military target system for being impacted by military rounds fired by a military weapon. 
     In one aspect, the system includes a base and a stationary member having a length and fixedly secured to the base and extending upwardly therefrom. A rotating member is positioned over the stationary member and has a length that is less than the length of the stationary member. 
     A bearing is located between the stationary member and the rotating member to permit substantially free rotation of the rotating member relative to the stationary member. A plurality of target sides are spaced apart around and fixedly secured to the rotating member in an outwardly extending orientation so as to promote rotational movement of the rotating member when hit by a fired round. 
     Side shields are secured to adjacent ones of the target sides. The side shields are provided by elongate rectangles of a length to substantially cover the rotating member without interfering with rotation thereof, and of a width to contact adjacent ones of the target sides close to the rotating member, but slightly spaced from the rotating member to substantially shield the rotating member from being hit by rounds. 
     The target systems are configured to withstand repeated hits from military rounds, and move in response to a hit to indicate that a fired round has directly hit the target sides. A further advantage is provided in that the target systems are immediately ready to receive further fire without the need to be reset. 
     In another aspect, the disclosure relates to a base, a stationary member inclined from the base and having a cap, a rotating tube having a cap and positioned over the stationary tube, a bearing between the caps of the stationary member and the rotating tube to permit substantially free rotation of the rotating tube, and a plurality of target sides secured to the rotating tube, with impact of a fired round onto one of the target sides initiating movement of the rotating tube relative to the stationary member.

     DETAILED DESCRIPTION 
     With reference to the drawings, the disclosure relates to a military target system  10  configured to withstand repeated hits from military rounds, that moves in response to a hit to indicate that a fired round has impacted the target; and is immediately ready without the need to be reset. 
     The target system  10  includes a base  12  having a base shield  14 , a transport sled  16 , a stationary tube  18  rising from the center of the base  12 , a target mount tube  20  sized to slide over the stationary tube  18  and to rotate relative thereto, a bearing  22  located at the top of the stationary tube  18  for permitting rotation of the target mount tube  20 , a plurality of target sides  24   a,    24   b,    24   c,  and  24   d  extending from the target mount tube  20 , and side shields  26   a,    26   b,    26   c,  and  26   d  between the target sides  24   a - 24   d  to shield the target mount tube  20  from damage. 
     The components of the target system  10  may be made of a durable material such as hardened steel plate, with the components welded for assembly. Suitable steel materials include one-half inch AR500 hardened steel plate and one inch A36 steel plate. The targets are compact and easily transported by dragging or by a forklift. In addition, the targets are devoid of any non-recyclable materials and may be readily recycled at the end of their life. 
     The base  12  is provided as by a flat steel plate and the base shield  14  is provided as by peripheral outwardly angled sidewalls  30   a - 30   d  extending upwardly from the periphery of the base  12 . The sidewalls  30   a - 30   d  are configured to provide a shield structure to protect lower portions of the target structure from impact from military rounds, with the angle of the sidewalls deflecting rounds away from the target. In addition, the tub-like structure provided by the base  12  and sidewalls  30   a - 30   d  readily accepts sandbags, concrete, dirt or the like if additional weight is desired. Drainage holes may be provided through the base  12 . 
     The transport sled  16  may be utilized to enhance portability of the target system  10 . The sled  16  may be provided as by a pair of cross members  32   a  and  32   b  welded to the lower surface of the base  12 , with a pair of runners  34   a  and  34   b  oriented perpendicular to the cross members  32   a  and  32   b  and welded thereto. 
     The stationary tube  18  is an elongate cylinder welded to a central location of the base  12 , having a cap  18   a  welded onto its upper end. The end of the tube  18  that is welded to the base  12  is cut at an angle so that the tube  18  extends upwardly at an angle a ( FIG. 3 ) that is greater than 90 degrees, so as to be inclined from vertical. A preferred angle is 100 degrees (from horizontal) so that the tube  18  is canted 10 degrees from vertical. The orientation of the tube  18  as described renders the target sides&#39;  24   a - 24   d  also at the same orientation which is advantageous to enable the range officer positioning the target system the option of desirably directing the ricochet of rounds. For example, rounds striking from the direction of incline will be directed downwardly into the ground. Conversely, rounds striking from the opposite direction will be directed deeper into the impact area. In addition, it has been observed that the angle also aids in improving visibility of the target systems from the air. 
     The target mount tube  20  is configured as an elongate cylinder sized to slide over the stationary tube  18  and to rotate relative thereto. The tube  20  is shorter than the tube  18 . A cap  20   a  is welded onto the upper end of the tube  20  and positioned to be adjacent the cap  18   a,  with the bearing  22  located between and bearing against the caps  18   a  and  20   a  when the target mount tube  20  is positioned over the stationary tube  18  to permit substantially free rotation of the tube  20  relative to the stationary tube  18 . The bearing  22  may be a ball bearing. 
     The target sides  24   a - 24   d  are shaped in a desired manner and welded to the target mount tube  20  and the cap  20   a,  preferably uniformly spaced apart to extend outwardly from the tube  20 . The upper portions of the sides&#39;  24   a - 24   d  which are configured to engage the cap  20  substantially protect the cap  20  from being hit by rounds. The sides&#39;  24   a - 24   d  have a length substantially corresponding to, but slightly longer than, the length of the target mount tube  20 . The side shields  26   a - 26   d  are secured to adjacent ones of the sides&#39;  24   a - 24   d  by welding and are provided by elongate rectangles of a length to substantially cover the target mount tube  20  without interfering with rotation, and of a width to contact adjacent ones of the sides&#39;  24   a - 24   d  close to the tube  20 , but slightly spaced from the tube  20 . As will be appreciated, the shields  26   a - 26   d  substantially prevents rounds from hitting the tube  20 . 
     The sides&#39;  24   a - 24   d  are configured as shown in the drawings to resemble the shape of a human. In one manner of use, a plurality of the systems  10  are arranged on a military target range in groups to resemble anticipated enemy tactical formations. Trainees, such as gunners and assistant gunners, equipped with machine guns or other direct fire weapon systems utilize rotary of fixed winged gunships to learn the art of searching and traversing with a machine gun or other direct fire weapon systems. The target systems provide the gunner and assistant gunner instantaneous audible and visual indication of direct hits to the target. 
     In this regard, it will be appreciated that the outwardly extending orientation of the sides&#39;  24   a - 24   d  from tube  20  promotes rotational movement when hit, with a “direct hit” being understood to refer to a fired round hitting one of the sides  24   a - 24   d.  A round that hits one of the shields  26   a - 26   d  or other parts of the target system  10  will not tend to impart such a rotational movement of the tube  20  relative to the tube  18 . 
     The spinning motion or movement of the target systems when directly hit advantageously indicate a direct hit, with the sound of the round hitting the target also providing an audible indication. The transfer of energy from the round into movement also reduces damage to the target systems from the rounds. Also, the target systems do not tip-over or experience any change that requires manipulation for subsequent use as a target, and are ready to receive fire even if still spinning from a prior hit. 
     Accordingly, it will be appreciated that the target systems described herein are sufficiently durable to withstand repeated hits from military rounds, move in response to hits; and are immediately ready without the need to be reset.
