Basic Main Combat Infantry:
10xINF [+ ART/ENG] (20 width)
Cheap and affordable, but not much else. Good on defence. Useful for poor minors.

Intermediate Main Combat Infantry:
7xINF + 2xART [+ ART/AT/EN] (20 width)
Same as above, but much better when attacking. Good for minors.

Deluxe Main Combat Infantry Division:
7xINF + 2xART [+ ART/AT/AA/ENG/LOG] (20 width)
Good all-around division that can fend off tanks on it's own and even inflict minor losses to air units. LOG means you can squeeze in more divisions per Supply Region (great for GER / SOV / USA), ENG gives a good advantage when defending. Good for majors.

XL Deluxe Main Combat Infantry Division:
8xINF + 2xART [+ ART/AT/AA/ENG/LOG] (22 width)
Same as above, just with an extra INF to get to 22 frontage. Good for majors with an Offensive leader.

Mass Assault Division:
10xINF + 2xART [+ART/AT/R-ART/ENG/LOG]
Adjusted template that adds a few extra INF divisions to make use of the -0.4 frontage reduction from the Mass Assault Doctrine tree.

Heavy Infantry DIvision:
6xINF + 2xART +1x H-TD [+ART/R-ART/ENG/LOG] (20 width)
A somewhat pricey, but extremely effective Infantry design. Protected against units without dedicated pierce and quite strong against enemy armor designs at the same time. A great option for late war countries like USA or SOV that have the time to grab HARM II tech before going into the fray.

Artillery Division:
4xINF + 4xART [+ ART/R-ART/LOG] (20 width)
Has lower ORG than regular Infantry, but more firepower per frontage. Good for breakthroughs.

Anti-Tank Division:
4xINF + 2xAT [+ AT/ENG] (10 width)
Great balance between SA, HA and cost. Keep them in reserve and use them in large stacks (8+) to halt enemy armored spearheads.

Anti-Air Division:
2xINF + 6xAA [+ AA/ENG] (10 width)
Low ORG, but high AA. Keep them as a +eserve in the rear and strat redeploy them into important battles where the enemy airforce is harassing you.

Armored Spearhead:
2xSP-ART + 3xARM + 4xMOT [+ ART/AT/MAIN/LOG] (20 width)
Has great SA, good HA and decent ORG. A good spearhead and breakthrough division that can hold against counter-attacks.

Assault Gun Division:
4xSP-ART + 2xARM + 2xMOT [+ART] (20 width)
Incredible SA that rips through enemy Infantry, with (barely) acceptable ORG value.

Mixed Armor Division:
2xSP-ART + 3xARM + 1xTD + 3xMECH (20 width)
Mixed armor division that can deal with any situation.

Motorized Division:
7xMOT + 2xM-R-ART [+ART/REC/ENG]
A fast division with decent speed modifiers. Even rivers won't stop these guys.

Security Division:
5xCAV [+MP]
Partisan supression unit

Garrison Division:
4xINF + 2xAA [+ENG/AA]
A defensive unit designed for island garrison duty where enemy air power is more threatening than tanks.
