The TM-46 and TMN-46 metallic antitank mines both have the same basic physical characteristics.
The only difference is that the TMN-46 has a fuze well for booby trapping purposes located on the bottom of the mine.
Both mines employ the
MV-5 pressure fuze and the MD-2 detonator.
Each mine has a 200 g (7 oz) TNT booster charge embedded within the charge.
They can be laid by all of the standard mechanical minelayers.
