I'd extend the HEAP table on page 141 to higher tech levels:
TL Multiplier
9 12
10 15
11 18
12 21
13 23
14 26
15 30
16 36
(These are HEAP equivalents of the various explosive power sources on page 67,
which I'm taking as representative of maximum energy densities at higher
tech levels. I suppose they'd get new names, since they aren't high explosives
any more - TL10-11 is "PlAP (Plasma Armor Piercing)", TL12-13 is "PPlAP"
(pulse plasma armor piercing) and TL14 is "FAP" (Fusion armor piercing).
This should let infantry-carried HEAP rounds be a little more respectable
against (at least) light tanks.
