Enjoyed this but it felt like it needed a clear goal. Liked the mechanic of trying to keep the soldiers supplied with everything they needed and I can see that if you added a "survive for X seconds" or "X enemy remaining" and then move to another level with different placement of people and equipment then it would move from good to awesome!
Oh and one tiny thing. Might want to make it more clear that the sandbags go to the walls and maybe have the ability to drop what your carrying. The icon doesn't match for the sandbags and my first game had me running round carrying a sandbag that I didn't know what to do with and couldn't get rid of until I died.
PS. Please rate my game!
