I wouldnt agree with previous comment at least on one point: about "tank-hunters" commander, especially with introduced changes.
You see,
1)this commander already have a lot of low-CP abilities, like Mines, AT-cons package, and so on, so there is no need in others.
...
Actually tank ambush should be a higher CP ability.
AT mines could be merged into 1 ability with tank traps.
Tank traps are not their to provide cover but to slow down tanks make them turn and expose their vulnerable rear/side armor.
Armor detection should not come with PTRS the bonuses of the PTRS are simply too many, camo, AT grenade assault, first strike bonus, armor detection. The upgrade is simply one of the most cost efficient upgrades on a cheap infantry to begin with. (That is why I suggested moving the upgrade to Penals). The unit feel allot more "elite" than "low trained conscripts".
