My wife is in the forces. She's in the med centre right now because her forty year old rucksack is literally destroying her back. And she's having to buy things like proper boots and hearing protection (so that she hopefully doesn't end up with lifelong hearing loss or tinnitus like many soldiers do) out of her own pocket because the army can't afford them.
When the army talks about "putting off new equipment purchases," that's what they mean. Good people, who want to serve our country, having their bodies literally destroyed by shitty, outdated, substandard equipment, so that we can save a couple of dollars on our taxes.
