This paper presents engineering models for the penetration of undeformable drummers into obstacles: wood, concrete, steel and water. As undeformable drummers used: special sniper rifle bullet VSS, concrete artillery shell caliber of 152 mm, the warhead of a concrete-piercing unguided aviation missile S-8BM caliber of 80 mm, armor-piercing shell of 30 mm caliber, bullet of a submarine special APS submachine gun with a caliber of 5,66 mm, bullet of submachine gun special two-mediums ADS with a caliber of 5,45 mm.It is assumed that the resistance force of medium can be represented as the sum of three forces: dynamic drag forces proportional to the square of penetration rate, the velocity of the medium in proportion to the penetration rate and the strength of the static resistance of the medium, which is independent of the penetration rate.Penetration calculations of typical drummers were performed that are in satisfactory agreement with empirical formulas. The listed models are necessary for solving military-applied tasks of penetrating ammunition into obstacles.
