Under the right circumstances, blockade can be a determining factor across the range of military operations, from coercion to major war. This paper tests blockade's potential in the 21 st century against the backdrop of three modern case studies -the U.S. blockades of North and South Vietnam, the coalition blockade of Iraq, and the Israeli blockade of Lebanon/Hezbollah. Blockade is analyzed in the context of the operational factors of time, space, and force, as well as its indirect effects on an enemy. The significant role technology and politics can have are also noted. Finally, this paper addresses the paucity of doctrine and written guidance to properly employ blockade, and makes recommendations to improve the visibility of this operational tool in the joint mindset.

This paper reports on the structural and optical properties of Co-doped TiO2 thin films grown onto (0001)Al2O3 substrates by non-reactive pulsed laser deposition (PLD) using argon as buffer gas. It is shown that by keeping constant the substrate temperature at as low as 310 degrees C and varying only the background gas pressure between 7 Pa and 70 Pa, it is possible to grow either epitaxial rutile or pure anatase thin films, as well as films with a mixture of both polymorphs. The optical band gaps of the films are red shifted in comparison with the values usually reported for undoped TiO2, which is consistent with n-type doping of the TiO2 matrix. Such band gap red shift brings the absorption edge of the Co-doped TiO2 films into the visible region, which might favour their photocatalytic activity. Furthermore, the band gap red shift depends on the films' phase composition, increasing with the increase of the Urbach energy for increasing rutile content.
