With his extensive military training, Castle is well versed in conventional and unconventional warfare. He is a master military strategist and tactitian. Castle is proficient in not only basic infantry skills, but in special operations which includes the use and maintenance of specialized firearms and explosive ordnance. He is also thoroughly trained and experienced in guerilla warfare and counter terrorism. He is highly trained in various forms of camouflage, stealth and infiltration into heavily-guarded enemy territories and structures for the purpose of Search and Destroy, Combat Search and Rescue or Reconnaissance missions. Castle is a skilled Paratrooper and Frogman. His hand-to-hand combat skills are more than sufficient to allow him to incapacitate and kill men much stronger than he is, as well as to deal with groups of armed and unarmed enemies, killing them all without weapons if he deems it necessary. He is also extremely deadly in knife fighting, preferring the knife he learned to fight with in the USMC: the KA-BAR. In addition, he is a trained combat medic capable of providing battlefield medicine. Castle's military training and his years of vigilantism have made him a master of interrogation and coercion. He achieves this through brutal intimidation either by physical or psychological tactics. Castle has also displayed an exceptionally high tolerance for pain, allowing him to undergo surgery without anesthesia.

Weapon
The Punisher's ever-changing arsenal of weaponry includes automatic and semiautomatic rifles, shotguns, handguns, fragmentation and tear gas grenades, other various explosives, and combat knives. He maintains and stores all his weapons and supplies in warehouses and safehouses throughout New York, New Jersey, Connecticut and other states.

The Punisher often customizes his weapons for greater effectiveness with both standard and custom items including magnified optics, reflex sights, night vision scopes, flashlights, grenade launchers, sound and flash suppressors, bipods, high-capacity magazines and ammunition including hollow point and armor piercing bullets.

Throughout the Punisher's crusade, he occasionally uses high-tech vehicles. His early series feature "battle vans" specially built and customized by his then-partner, Microchip. These vans were heavily armored, loaded with high-powered ammunitions with advanced telecommunication capabilities. Castle used these vans for surveillance and weapons transportation. He has also used motorcycles, helicopters, speed boats, or whatever else he could find and use.

At one point, the Punisher had a pet Rottweiler, "Max", which he had saved from a dog fighting ring.
