TL3 shields work as cover vs modern rifles?

As a large shield like the roman ones are a meter high and 2/3 wide, they fully cover the body when just held, though they do not give any DB against firearms...

So a modern trooper firing at legionaries would according to gurps have to aim at heads/legs or hands as a assault rifle will not damage the chest.

An m16 will do 5d dame that is on average 17.5. Whereas the shield has a DR of 9 and 60 hp and according to the breaking shields rules is penetrated on HP/4+DR, thus with 24 points. Add the RD 5 chest armor and the total raises to 29 that requires one to roll five sixes to penetrate one point.

And on everage would need 7 hits to eat away the hitpoints of the shield. (60/(17.5-9))

Now take situation 2: same large shield, but iron version, with the enemy crouching behind the shield as to not give targets: to damage him would require: DR 12+ 120/4=42 points.. that is impossible to get.. so only eating though the shield HP will work.. that takes on average 21 hits.. (120/(17.5-12))

Situation 3: a 50 cal HMG from basic set raking a group of enemies from situation 2 that have a heavy steel corselet and heavy plate arm:
effects of those rounds that hit:
no penetration of shield: 26%
no penetration of shield+arm/torso armor: 42.5%
less that 10 hp damage(max 5 pentrate armor), so likely survive: 21.5%
more likely deadly(6+ points penetrate armor this 12+hp damage): 10%

Somehow.. seems bit wrong..
