It is possible to fight without any weapon at all, either in hand-to-hand combat (i.e., kicking and gougng) or in regular combat (punching). The damage a figure does in bare-handed combat is ruled by his strength. In unarmed regular combat, a human or humanoid fighter does damage as follows:

Other kinds of bare-handed combat do more damage. A fighter in HAND-TO-HAND COMBAT does the appropriate amount of damage for his ST as above, plus 1 - that is, a ST 9 fighter does 1D6-2 damage. A fighter with the UNARMED COMBAT talent rolls one extra die for damage - so a ST 9 fighter does 2d6-3 damage. A figure with one of the Unarmed Combat talents does extra damage when fighting bare-handed; When a lighter uses a dagger or cestus in HTH combat, the damage done is also based on the table above. A fighter using a dagger, cestus, or main-gauche does the damage appropriate to his ST on the above table, plus 3 . . . so a tighter with ST 9, using a dagger in HTH, would do 1 die damage. When a fighter uses a club in regular combat, damage done is also ruled by the above table. Add 3 to the damage shown above for a one-handed club, or 4 for a two-handed rnaul, used by a lighter of a given ST. A giant of ST 35, with a one-handed club, would do 2 + 4 damage when he hit.
