But then it just recently dawned on me: With halftracks you can embark edit: disembark of course

This far outweighs the extra Attack stats. It has so many tactical benefits its crazy.
On Generalissimus mode its a real hassle to get your Pioniere in striking distance without exposing them.
Every pesky scoutcar or cavalry really hits hard if it catches them in the open or still embarked in a forest tile (not to mention tanks!). And setting up defensive artillery will only soften the blow from very bad to still bad.
You cant afford constant replacement on this difficulty.
To me, that translated in setting up my advance with screening units for the Pioniere.
This of course just slows the advance.
But if u can disembark your Pioniere in forest and hill tiles, it completely changes. Due to the close defense mechanics and the insanely high close defense of Pios, they just become irremovable objects.
No one attacks them.
This not only relieved me of the burden to screen them - I can now use them to screen others. You can even let them be the outer part of an encirclement, that faces a likely counter attack. It kinda changed the whole game for me lol
P.S.: I know there is a thread already about halftracks. I'm guilty
