[[Vacuum suit|Pressurized suits]] are a necessity during EVA operations due to the vacuum of space. In addition, [[thruster pack]]s are needed for maneuvering when not tethered to a spacecraft. Combat EVAs pose a significantly greater risk to those performing it, due to the chance of suit decompression in the vacuum if hit by bullets, shrapnel, etc. [[Civilian]] welders and technicians perform EVAs in order to repair ships, such as that performed upon the {{UNSCShip|Gettysburg}} in the [[Eridanus system]].<ref>'''[[Halo: First Strike]]''', ''page 90'' (2003 edition); ''page 336'' (2010 edition)</ref> The UNSC also employs specialized EVA-equipped engineers on their warships such as the {{UNSCShip|Spirit of Fire}} to perform repairs and maintenance work on the outer hull.
