Chest

Chest is a hit location introduced in GURPS Low-Tech when the Torso was divided into that and abdomen.
An upper chest location is also targeted at -1 per Instant Armor page 20's description of Pectorals which in addition to protecting vitals had a 1/6 to 5/6 chance (during random hits) of stopping attacks aimed there. Upper chest is location 9 (not 10) on the new random hit location tables, so lower chest is presumably location 10.
To avoid the random chance of pectorals protecting the upper chest requires taking additional penalties to the -1 depending on the cost/weight percentage.
