This A4 page is a 3x3 PDF layout (see the thumbnail to the right) of the card shown here to the left. It can be used to tick off END as it's expended, and a separate card should be kept for each piece of equipment (or even for each battery). Notice that there is a line which runs "Expend_______END per________________" — that is to accommodate my Reduced END variant which allows some equipment to expend END over longer time periods than per Phase.

If for some reason you can't (or won't) open PDF files, you can save the GIF image to the left and print from that, but I wouldn't recommend it as a first choice.
This page links to all the HD2 templates, characters, vehicles, gadgets and so forth I use in my campaign. To save them for your own use, right-click on the links and select "Save target as..."
