Learning to write a concise argument (within a specified range of pages) is a valuable lesson, meeting the minimum page length should never be the sole factor that disqualifies a person.

"Offensive weapons
Laws of the late Viking period show that all free men were expected to own weapons, and magnates were expected to provide them for their men. The main offensive weapons were the spear, sword and battle-axe, although bows and arrows and other missiles were also used. Weapons were carried not just for battle, but also as symbols of their owners' status and wealth. They were therefore often finely decorated with inlays, twisted wire and other adornments in silver, copper and bronze.
The spear was the commonest weapon with an iron blade on a wooden shaft, often of ash and 2 to 3m in length. It was used for both thrusting and throwing. The blades varied in shape from broad leaf shapes to long spikes. Skilled spearsmen are said to have been able to throw two spears at once using both hands, or even to catch a spear in flight and hurl it back with deadly effect.
Swords were very costly to make, and a sign of high status. The blades were usually double-edged and up to 90cm, or a little over, in length, but early single-edged sabres are also known. They were worn in leather-bound wooden scabbards. Early blades were pattern-welded, a technique in which strips of wrought iron and mild steel were twisted and forged together, with the addition of a hardened edge. Later blades of homogeneous steel, imported probably from the Rhineland, bore inlaid makers' marks and inscriptions, such as INGELRII or ULFBERHT. Viking craftsmen often added their own elaborately decorated hilts, and many swords were given names, such as Leg-biter and Gold-hilt.
Long-handled battle-axes might be used instead of swords, particularly in open combat. The famed, double-handed broad axe is a late development, typical of the late 10th and 11th centuries. But as the owner could not hold a shield at the same time, he would take cover behind the front line of warriors, rushing out at the right moment to hew down the enemy."
