They look cool, but did they have full military gear just no rifles?
None of the gear is military. They're wearing civil defense uniforms and civilian helmets, which are made of a cheaper metal than real helmets.
Civilian men at the time were also encouraged to wear kokumin fuku or "national clothes," which were patterned after military uniforms but not actual uniforms; people carried a bag with a first aid kit, triangular bandage, and a canteen. So it may look like they have military uniforms and gear, but it was all private purchase.
Depending on how the spear-armed militia do, militia with old rifles is also a possibility.
