absolutely right
Absolutely not.
1. They don't cost as much as suggested for what they get.
2. You don't kill their ai capability as much as suggested. They will still beat most unupgraded axis infantry closerange even when equipped with piat/s.
3. They can and will kill heavy/medium vehicles with piats as they have elite version of piats. By this I mean that they will behave in a largely similar way to pzgrens with shrecks plus will have more durability. (It is really curious how some forum members keep demonizing shrecked pzgrens but are worried about "wasting" their own elite infantry when equipping them with bazookas/piats and downplaying their effectiveness).
4. Retreating out of camo is not a big thing, as they will often pop smoke and have 5 men. They're not a sniper and they are very forgiving. Even without vet smoke they will be fine.
5. Keeping 222 for scouting is much more difficult than allied lights.
6. Complaining about elite infantry with piats moving head on straight in between axis units and, for some reason, can't be seen is not pathetic. It is justified and much less pathetic than being afraid of 4men visible pzgren squads. The mechanics of moving half the map full speed cloaked in front of enemy troops in just ridiculous.
7. Spending 100 munitions to kill a vehicle is actually a very good trade, especially that the piats remain on the infantry that will safely return to base.
8. There is a commander in ost rooster with camo. The ability occupies the whole commander slot, you need to pay extra to make it possible for a given unit to equip it, and on top of that it works only when stationary and in cover. Oddly enough, it was considered broken and OP.
