Roman army of the mid-Republic x 700m = ca. 50 hectares). Along the perimeter, a ditch ("fossa") would be excavated, and the spoil used to build an earthen rampart ("agger") on the inside of the ditch. On top of the rampart was erected a palisade ("vallum") of cross-hatched wooden stakes with sharpened points. Within this precinct, a standard, elaborate plan was used to allocate space, in a pre-set pattern, for the tents of each of the various components of the army: officers, legionary infantry (split into "hastati", "principes" and "triarii") and legionary cavalry, Italian allied infantry and cavalry, "extraordinarii" and non-Italian allies. The idea was
Electric fence stakes at the bottom, designed to be driven into the ground with the foot. For a hand-tightened temporary fence of electrified rope or web in a small area, these are usually spaced at no more than 12 to 15 feet (about four metres) to prevent the fencing material from sagging and touching the ground. Larger areas where tools are used to stretch wire may be able to set step-in posts at larger distances without risk that the fencing material will sag. With temporary electric fencing, a large area can be fenced off in a short period. Temporary fencing that is
