|Indoor environment is one the difficult environment which denies access of ground armored vehicles, which force soldiers to get out of the armored vehicle and clear out the buildings. In guerilla warfare, short range combat is common since enemy is not in military uniform and military vehicles which enemy is blended into the public, risking ambushes and forcing close combat. Indoors, situational awareness is limited for massive obstacles in the way limiting what soldiers could see. Traps could be easily hidden within indoors, and soldiers are at risk by grenades and explosives thrown. UGV operation in door is also difficult for doors, stairs and other obstacles on ground. Wheels and catapillars are still limited in flexibilty when facing tall obstacles. While arm units may be attached to open doors, UGVs with feet may be a solution to climb over obstacles but lacks mobility than wheels and catapillars (maybe a leg-wheel hybrid for speed and flexibility?). Walls may cause problems for wireless communication. While powered suits may provide protection indoors against grenades and certain explosives, current exoskelton programs seem to deny indoor use, for exoskeltons which are based on gas, probably because of the toxics that may cause breathing difficulties for the sealed room.
What are the solutions for indoor combat especially against insurgency, and how effective would powered suits and UGVs be indoors? What are the constrains, and what may be useful for indoor combat for survivability? What sensors and communication gear maybe useful indoors?
