''The C3A1 is a Canadian produced blast/shape charge antipersonnel mine. The C3A1 is nicknamed the ELSIE. The mines pointed end is pushed into the ground so as only to expose the top portion of the mine. The shipping plug is removed and the charge assembly with safety clip is inserted into the mine body assembly. Once emplaced into the ground, the safety collar of the mine is removed to arm the mine. Mine will actuate when 7-12 kg force is applied. Upon activation, an explosive charge will detonate sending explosively formed penetrator upward. This mine is in service with the Canadian and British Army. The US and Japanese copy of this mine is called the M25 and Type 67, respectively.''
