You stall for the unit so you can get more than 1. The more of these elite anti-infantry units you have the better, since together they are more likely to wipe an enemy squad before the enemy responds - however, if you first have to get a large number of regular infantry units, you can't get more than 1 of the elite infantry units because you'll run into Man Power problems for other units like tanks and AT guns.
As for why UKF is bad:
- No stock assault troops. The only stock unit that has a close range weapon doesn't have grenades either.
- Overly punishing cover mechanics which makes Tommies very vulnerable against assault troops when caught in the open (to get decent DPS you first need to get to cover, by that time the assault troops are already in grenade throw range) and make them poor at flanking.
- No stock elite infantry
- Short on anti-tank snares compared to all other factions
- No useful stock anti-garrison tools
- Awkward healing mechanic which makes using units like snipers more micro-intensive.
- Multiple stock units are useless in 1v1s like Bofors and 14 pounders, and some stock units are exclusive which limits flexibility.
- Mortar pits aren't great and they can't be because their design sucks.
OK,
Soviets don't have stock assault troops either.
Your saying tommies with their 0.9 RA and 5 men are more vulnerable to assault troops that have combined dps ranging from 51 to 75 than grenadiers with their 0.91 RA 4 men against assault troops with dps ranging from 67.5 to 94 and with no cqc grenade to protect them. That's a very untrue statement man.
Soviets also don't have stock elite infantry and can the officers be considered elite infantry in USF???
The snare thing is true.
I'm pretty sure grenades counts as stock anti garrison tools.
How is a mechanic that allows you to heal on the field without having to retreat an awkward thing. Clearly you are too busy thinking other stuff is better than see why this mechanic is awesome. In coh1 the self healing on axis squad was a pain in the ass to deal with.
How is the bofor useless in 1v1.
The mortar pits design doesn't suck. Use it, screen for it. Your the brits why would you be attacking.
